Created attachment 108436 [details]
Dump of serial console during bootup... up to hang on shutdown.

Summary: I can start Xorg *once* just fine, also switch to/from text-consoles. But once this X-server ends, both monitors will turn black and go to powersave.

After this has happened, a new X-server will hang. Also a clean reboot is no longer possible, because also the shutdown-code running in the Kernel will hang with a similar stack trace.

This bug is reproducible 100%.

Hardware: NVIDIA Corporation G86 [Quadro NVS 290] (rev a1)
          BOOT0  : 0x086f00a2
          Chipset: G86 (NV86)
          Family : NV50

Platform:     amd64
Linux-Kernel: 3.18.0-rc1
Distribution: Arch-Linux

Xorg server: xorg-server 1.16.1-1 (from Archlinux repository)
Xorg driver: xf86-video-nouveau 1.0.11-2 (from Archlinux repository)

Everything looks pretty unremarkable while using the computer normally running X which is very stable, can run for days. Also terminating the X server looks uneventful.

/var/log/Xorg.0.log on normal X-server start up to termination

Starting and stopping the X-server the first time looks unremarkable.

Can you bisect? I assume this wasn't an issue in 3.17?

Disassembly of nouveau_pmops_runtime_suspend

As the only nouveau-specific thing in the kernel-stack-trace seems to be nouveau_pmops_runtime_suspend, I'm adding a disassembly.

Unfortunately the two calls to pm_runtime_forbid() can't even be distinguished, as there's only one call, and the 2nd one is optimized by gcc to a branch upwards, I've marked the actual location from the stacktrace with #####.

> Can you bisect? I assume this wasn't an issue in 3.17?

Sorry... I've not mentioned that. It is an issue since I put in the Nvidia card, about ... over one year, to be sure. I just wasn't sufficiently annoyed until now.
Comment 5 Ilia Mirkin 2014-10-26 11:01:48 UTC
Seems like you're being hit by runtime pm somehow... Can you confirm by booting with

nouveau.runpm=0

to see if that resolves your issues? runpm was new in kernel 3.12 iirc (for nouveau).
Comment 6 Christian Vogel 2014-10-26 18:42:03 UTC
(In reply to Ilia Mirkin from comment #5)
> nouveau.runpm=0

This fixes the issue with the hung X-Server, I can terminate and re-start
X-servers as expected when logged in via ssh.

But parts of the bug remain, namely that the X-console will freeze as soon as the VT on which the X-server was active is selected:

 - system boots, X-server works, I can login, use applications

 - stop lightdm -> X-server turns off, screen goes black, keyboard does not work

 - via ssh: start lightdm -> X-server restarts, everything looks ok again

A funny variation of that theme:

 - system works, running X

 - switch to VT2 (Ctrl-Alt-F2), I get the linux vt #2, everything ok

 - on the console (or via ssh): stop lightdm
     -> nothing visible changes, X terminates in the background

 - switch to VT3 (Ctrl-Alt-F3), I get the linux vt #3, all ok

 - switch to VT1 (Ctrl-Alt-F1) where the X-server was active before:
     -> cursor stops blinking, keyboard no longer responsive, screen
        content frozen

 - via ssh: start lightdm
     -> X server starts up, I can login into X and use applications,
        keyboard works (actually, that's how I write this text now...)

 - switch to VT2, VT3, ... works now.


---> Why does the framebuffer-console hang when I change into the
     VT previously occupied by nouveau/xorg?
Comment 7 Christian Vogel 2014-10-26 18:43:30 UTC
(I want to add: For a user that doesn't have a second machine to ssh remotely, or to have a serial terminal, the end result is probably the same than with nouveau being hung in powermanagement -> No other way to get the machine working than to reset/restart.)
Comment 8 Dāvis 2015-08-13 01:47:02 UTC
I've same issue, but on Arch Linux 4.1 with NVIDIA GeForce GTX 650 Ti
nouveau crashes kernel that can't even reboot/poweroff, only with hard reset.

adding nouveau.runpm=0 to kernel parameters atleast it doesn't crash.
