dmesg after crash
Following comment #8 in https://bugs.freedesktop.org/show_bug.cgi?id=61321 (which deals with the same GPU), the problems go away if I boot 3.7.9 with nouveau.noaccel=1. Of course, this means that glxgears and vmd run without crashing the X11 session, *BUT* without acceleration. In particular, vmd without acceleration is unacceptably slow for me, so running without acceleration is not an option... However, this reinforces the idea that the problem is definitely related to acceleration. Created attachment 83730 [details]

I got same error on i686. linux 3.10.4-300.fc19.i686.PAE #1 SMP VGA NVIDIA Corporation NV31 [GeForce FX 5600XT] Gabriele Can you try booting with "nouveau.config=NvPCIE=0"? It will force nouveau to use nv04 style vm and could handle your issue If that does not work out, can you redo the bisection ? Georgy Please open a separate bug following the instructions [1] Cheers Emil [1] http://nouveau.freedesktop.org/wiki/Bugs/ See https://bugzilla.kernel.org/show_bug.cgi?id=50091 Bisection is utterly broken. hello, I am presently away from the machine which I reported the problem for and playing with remote reboots is too risky for me at the moment. However: for me the problem apparently went away somewhere in the 3.8.x or early 3.9.x window: at present (3.10.5) acceleration does work (only the vmd molecular visualization code seems to have problems with recent (>=9.1.x) mesa) Looking into my logs, I am pretty sure I tried this nouveau.config=NvPCIE=0 kernel opt, but with no success. I remark that, at present, the GPU seems to work fine with acceleration enabled: glxgears runs without problems and so is for vmd (with the mesa limitation mentioned above) This makes me think that the problem reported by georgy for the different GPU might be actually different. Also, frank: you are running the same GPU: did you try a recent (3.10.x) kernel? Unfortunately, I am not able to say exactly WHICH kernel version did the trick for me: I can try booting old kernels until I reproduce the problem, if that can be of any use. But I can do this only on monday next week ciao gabriele It definitely wasn't fixed up to the first 3.10-rc's. Although it was pretty reproducable in my case, it sometimes worked fine for a few minutes, so a quick test isn't enough. I doubt it will ever be fixed again. That's why I'm on Radeon hardware now. The original reporter's issues seem fixed. Feel free to re-open if I've misunderstood. I'm inclined to think that the NV31 issue is unrelated, looks like the fifo gets confused on that one. |

Hello, I am experiencing X11 problems with kernel>=3.7 (including latest 3.8 release) with the following GPU: NVIDIA Corporation C61 [GeForce 6150SE nForce 430] (rev a2) I am on an AMD Athlon 64 X2 Dual Core Processor, running in 32bit mode and using DRM/NOUVEAU in KMS. Further (possibly) useful information about software versions is: mesa 9.0.2 libdrm 2.4.42 xf86-video-nouveau 1.0.6 xorg-server 1.13.2 I can boot just fine in KMS. Also X11 (which I run with startx) boots nicely and is *almost* perfectly functional (which is why it took me a while to focus the problem) The problem is apparently related to acceleration: if I run glxgears (or vmd, a molecular visualization code which uses acceleration), the X server suddenly looks (to me) overloaded and unstable (e.g. I cannot move the pointer any more); within some 10-20 sec I can escape to the console with CTRL-ALT-F1 and just kill manually the X server with CTRL-c. This however takes a bit and in the meantime I get the following repeated messages (apparently) from some nouveau component on the console: nouveau E[ 891] failed to idle channel 0xcccc0000 After this, the GPU is apparently left in a sort of locked state: if I restart X, the screen shows the image just before the crash and is totally unresponsive. However, I can still shutdown X with CTRL-ALT-F1 and kill manually the server. In order to have X running again I have to reboot the machine. The problem is completely reproducible. If I boot into kernel-3.6.10 (everything else unchanged), nothing of the above happens and glxgears (and vmd) work absolutely fine. I have bisected the kernel commits from 3.6.10 to 3.7-rc1 in drivers/gpu/drm/nouveau/ and it turns out that: 612a9aab56a93533e76e3ad91642db7033e03b69 is the first bad commit commit 612a9aab56a93533e76e3ad91642db7033e03b69 Merge: 3a49431 268d283 Author: Linus Torvalds <torvalds@linux-foundation.org> Date: Wed Oct 3 23:28:59 2012 -0700 Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux Pull drm merge (part 1) from Dave Airlie: "So first of all my tree and uapi stuff has a conflict mess, its my fault as the nouveau stuff didn't hit -next as were trying to rebase regressions out of it before we merged. Highlights: - SH mobile modesetting driver and associated helpers - some DRM core documentation - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write combined pte writing, ilk rc6 support, - nouveau: major driver rework into a hw core driver, makes features like SLI a lot saner to implement, - psb: add eDP/DP support for Cedarview - radeon: 2 layer page tables, async VM pte updates, better PLL selection for > 2 screens, better ACPI interactions [...] Problems for the same GPU with kernel>=3.7 have been already reported here: https://bugzilla.redhat.com/show_bug.cgi?id=905629 However, it is not clear to me if that report and the present one are dealing with the same thing... Please, find enclosed: => kernel configuration => xorg configuration => xorg log after the crash => dmesg after the crash (To avoid possible confusion: I opened a bug here some time ago for another problem with another NVIDIA GPU (Bug 58776): in that report I said that this GPU was working fine: of course, I did not discovered yet the present issue) I thank you very much in advance for any help ciao gabriele
