I've tried downgrading to kernel 4.9.14, as the 4.10 series seems to have other changes relating to video drives and nouveau (which are also causing crashes).

I made it from ~8am to ~noon without a crash. Same basic log entries found in journalctl output:

https://bugs.freedesktop.org/show_bug.cgi?id=90453 Sounds related.

I have the same issue, on Linux 4.11-rc6. journalctl -b:

I'll post a proper dmesg the next time the bug appears.

dmesg with SCHED_ERROR (starting at 73576 sec)

It happened again! I believe the monitors were turned off when the problem occurred (I wasn't there at the time), but when I returned the monitors were on and frozen. I could move the mouse around, but nothing else responded.

The errors start at [73576].

journalctl -kb of CTXSW_TIMEOUT on 4.10.10

Can reproduce on Linux 4.10.10 as well. Along with the initial CTXSW_TIMEOUT, it seems to hang a few kernel tasks relating to atomic commits.

Same problem on 4.9.16-gentoo.

I've attached syslog and dmesg. 

In average the problem occurs every one or two days on my machine with one monitor, resolution 3440x1440. 


The x11-drivers/xf86-video-nouveau driver version is 1.0.15

dmesg

I think I am experiencing the same problem on 4.10.0-24-generic on Ubuntu 17.04 with GNOME 3.24. I have 1 monitor running an Nvidia card.

The desktop freezes between 20 mins to 5 hours of the system running from boot.

This is the system log when it crashes

Let me know if I need to provide more info

It must be a driver bug, as I see the same error on different kernel and different graphic hardware.

Same problem on Linux Neon 4.10.0-40-generic
xserver-xorg-video-nouveau-hwe-16.04 - 1:1.0.14-0ubuntu1~16.04.1

On my Lenovo P50 this problem is newly introduced since I use a 4.14 kernel. Kernels below that are stable/working in regard of that problem. This is what I can aquire from the logs:

I found this in my Xorg.0.log but I don't know if it's somehow related to the above:

[   155.535] (EE) libinput bug: timer event13 debounce short: offset negative (-2229)

This looks very similar to Bug 103721.

Hello there?!?!

Just because of pure curiosity: is any developer interested in this or are the users left alone watching their machines freeze for almost 10 months now?

Is there anything I (or any other user) could do to provide more info? Maybe apply a patch, send debug log, try this or that?

It's really so sad to see absolutely no progress but more complaints for that long...

I also have this problem with a 770 GTX since I switched to KDE 5 about 5 months ago. Freeze without reason learns exept the mouse cursor. 
Kubuntu 17.10, Kubuntu 18.4, Debian 9 KDE and KDE Neon, same problem. In addition, with the nVidia driver it's worse.

After switching driver to nvidia-390, I've similar crashes as per https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-390/+bug/1802050 & https://forums.geforce.com/default/topic/1098094/geforce-drivers/kernel-crash-at-_nv009384rm-os_memcpy_to_user-bad-or-missing-usercopy-whitelist-/

$100 offered for a RELIABLE fix _upstream_ Kernel/Nouveau/Mesa/... so that we all get rifd of this annoying bug!

No shit sherlock.

Somewhat surprised that this particular report hasn't received any attention from a core dev. Sadly, I'm afraid my response will not be hugely satisfying eiter.

The message "fifo: SCHED_ERROR 0a [CTXSW_TIMEOUT]" is not the result of *a bug* and does not point in the direction of one. Rather it is a symptom of a wide variety of potential problems with nouveau, (all of) which result in a hang of the rendering part of the GPU. On itself it doesn't give meaningful information to any developer as to what may be the culprit. It's like measuring a fever, it could be the result of many conditions.

Developers would be helped if there was a reliably reproducible situation in which this event can be triggered. If there is a list of steps that can be followed that would result in this message and a hang, that somehow doesn't involve words like "random" or "wait for possibly a few hours", and that can be traced with tools such as APITrace, we could get a step further in analysing what goes wrong. However, it seems unlikely this is the case, especially since we are also aware of multithreading-related issues that make isolating such problems extremely difficult. Unfortunately, post-mortem syslogs and dmesgs are unlikely to add any useful information to this or similar bug reports.

Hi Roy,

first of all thank you very much for your time taken to answer this thread. Also thank you for the insights you gave.

As there are "tons" of threads out there, from Ubuntu to Fedora bug trackers, as well as several threads here on freedesktop and the Linux bug tracker, that are open created even 2 years ago, I guess it's time to get hands on to get rid of this bug. You cannot imagine how annoying it is if you work on a machine that could easily just completely "stall" when you open the wrong menu item or scroll a Twitter page just at the wrong time.

Anyways, I'm still offering $100 for fixing this, so me and a good bunch of people around get this fixed upstream, so that it won't show up regardless of distro or whatever kernel they run. This definitely needs a good amount of backporting though, as it bugs us for a long time. Maybe the one or other is willing two throw another $5 at it, so this would actually not benefit the user only, but also the developer. If someone is familiar with a crowd-funding or something -> I am not.

I'm willing to participate in testing patches or whatever I can do as a non-graphics-driver developer. I'm surely familiar with the processes testing patches, however.

I don't know what to suggest as a start to get this thing done. I have nouveau "debug" logs on my machine for a long time, but actually never saw anything relevant in it besides the "message of death". Just a blink of an eye after this happens the machine is completely unusable - no chance to interact anyhow besides SysRq+REISSSUB.

I would very much like to make a progress here.

Maybe we could start and gather the already opened bugs and the people who participated in these. Just to have a couple of people really "hit" by the problem, that are willing to help and, moreover, are able to gather info on their machines.

I'm pretty happy to run my machines without the "BLOB" and would happily keep it this way. But this is a showstopper. A showstopper that has not gotten the right attention for a long time now.

Thanks in advance - no matter what we will achieve.

Marc

The best way to get a good experience is to avoid doing things which break nouveau. If you don't need the 3d acceleration, just remove nouveau_dri.so. You still get the X-based acceleration (via xf86-video-nouveau, not the GL-based modesetting driver), but no OpenGL. This gets you a fairly rock-solid experience.

Unfortunately software whose name starts with the letters G and K has come to depend on OpenGL for even the most basic tasks without much care about driver support for this in the past couple of years. I generally avoid those, and do just fine. (While I do run GL-using applications on occasion, I don't do it all the time, or many of them.)

While your offer for $100 is well-meaning and appreciated, the reality is that the capable developers either work for free in their spare time (at which point accepting $100 is probably more trouble than it's worth), or need stable full-time jobs (so a lot more 0's are needed on that offer).

Hi Ilia,

by offering a $100 for this the intention was to just get this thing sorted out from the nouveau guys _prior_ to any "my game X still doesn't work with nouveau" bug. I don't want to lean out toooo far out of the window, but I think this actually is a gregression, too. Not just a bug. Nevertheless, I know developers earn much more than that, I'm a developer myself.

I cannot share your expression "The best way to get a good experience is to avoid doing things which break nouveau". What experience is this if you use a product that you know has a bug and you try to avoid it? Someday you change the product. But I do not want this. I want the bug to be sorted out, offering my spare time, some bucks for you to have a night out and nothing more.

I use enlightenment desktop on top of modesetting driver with "nouveau.noaccel=0 nouveau.nofbaccel=1 nouveau.modeset=1 nouveau.runpm=0 nouveau.debug=disp=trace,i2c=trace,bios=trace nouveau.config=NvPmShowAll=true" applied. I see no reason to just _not_ use the features the driver offers. And when they do not work: either fix them or get rid of them.

I'm also absolutely not into heavy 3D, hevay OpenGL or whatever-usage. I just use a modern and advanced desktop environment (Enlightenment, git) on recent "stable" hardware (ThinkPad P50). Not trying to _force_ nouveau to go down.

If your answer really is to "not stress" the driver with a usual workload, avoid stuff "with the letters G and K" or whatever... oh dear. Cannot imagine how I start to argue over this for _my_ work with _my_ boss...

Yes, I'm quite concerned by the "just avoid the bug" mentality too. I first reported this bug because running a web browser, terminal, and text editor (as a web developer) on a default Fedora install was seemingly asking too much of the Nouveau driver. I wasn't taxing it with any unusual. I ended up switching to the proprietary driver because I couldn't be productive with so many crashes in the course of a work day.

I now work at a different place and no longer have access to the hardware where I was experiencing this issue, so I'm afraid I can't be of any further help here. I wish you all luck!

Seems I just hit this also on Fedora 30:

Although there is probably nothing new and/or useful here and given the lack of movement, I guess I will just go back to the nvidia driver, unfortunately.

14 days ago I went back to Nvidia BLOB after almost 3 years of noveau usage. So I at least can use my hardware without the unpredictable interruption which resulted in lost work also. Side effect: also have CUDA/OpenCL now.

On 'disco' aka:
uname -a
Linux ceo1homenx 5.0.0-19-generic #20-Ubuntu SMP Wed Jun 19 17:04:04 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

The following trace shows a nouveau problem, then two mintues later a kernel lock that requires a power cycle to recover from.   This is a system that has two graphics cards with all the available monitor ports (3) used.   These hard lockups happen two to four times per day.  This latest one was under a no load condition.  I walked away from a system with an email and firefox ap up.  An hour or so later I return to a locked system. It's becoming unusable.  Detail:

The nouveau driver on my ThinkPad P50 (running RHEL 7.7 with a 5.2.11-1.el7.elrepo.x86_64 kernel) just hung up with this same error.

What is possibly interesting is that in /var/log/Xorg.0.log
there was a mouse event that matches exactly with the timing of the nouveau errors.

[150270.473] (II) event8  - Logitech USB Receiver: SYN_DROPPED event - some input events have been lost.

The [bracket] is a timestamp which indicates the time since the system last booted, in seconds. So 150270 is 29 seconds after the 09:04:19 timestamped line. 
09:04:19 + 29 seconds is 09:04:48
The nouveau driver hung at that time (see /var/log/messages timestamp above)
Not certain if that was cause or effect of the video driver hang.

I was able to ssh into my system to reboot.

I've been using this 660Ti (NVE4) card with nouveau and tested several kernels: 4.14, 4.19 and 5.3, all with the same problem. During different usage or games, the system freezes. It is recoverable with SysRq + RE, though. It might be possible to SSH into the system and kill this process manually, but I'm not sure.

This freezes happens with multi-monitor and single-monitor setups. The machine has two videocards.

I also would love to help with traces, if anyone has ideas.

Same bug here. Seems to happen often with firefox, when opening a link, or when usintg alt+tab to switch to it. So I changed to chromium, which seems to trigger it at least not that often.

The bug as well recently happend when I switched to eclipse via alt+tab. Here a log:
