The nouveau driver hangs with mythfrontend.  My system is a desktop intel i7
onboard graphics running kde plasma and a separate user (seat) running
mythfrontend directly on X (not kde) using an nvidia GT240   The allows me to
use my desktop system at the same time the TV is running mythtv in an adjacent
room.  When the nouveau driver hangs it has no affect on the desktop system,
the last frame or menu remains static on the TV even after restarting the
mythfrontend application.

I can reliably cause the hang by stopping the video player using the remote
control then trying to stop it again before it completes the first stop.  I see
the last frame of video and the remote no longer works.  Restarting the
mythfrontend application, as root on the desktop, blanks the screen then the
last frame of video is shown on the TV even though the application has not
started a player.  Restarting should display a menu, but once hung the picture
does not change.

I suspect the some internal registers or kernel data structures are not
finished being cleaned up and the second stop does not allow this to complete.

I had to replace my graphic card now as the old one died now. So could these
problems arise from memory corruption in a dying card? I have now a GTX 550ti
which has not shown these error messages yet.

Hi Guys,

I've got the same  kind of issue.

Hang when starting up some software.
01:00.0 VGA compatible controller: NVIDIA Corporation GT218 [GeForce 210] (rev
a2)  (an prety old card).
nouveau :01:00.0: fifo: CACHE_ERROR - ch 12 [gwenview[13360]] subc 3 mthd
01a8 data beef0201
...
(only X/keyboard hang... ssh still working).


Cannot go to console... console didn't work with nouveau without fb.
(I had no more issue after recompile xscreensaver/flux).

Dominique

I tried to switch to modesetting driver, but my X sessions are crashing also. I
attached crash info recently.

Also QSG_RENDER_LOOP=basic was applied.

Is there any workaround available to avoid crashes? I do not need any 3D or
anything, just stable 2D desktop.

I attached a kernel trace which may be related. I got this when:

1. Upgraded Fedora 24 to Fedora 25.

2. Disabled wayland for gdm.

3. Created script with export QSG_RENDER_LOOP=basic in profile.d.

4. Logged in as a first user to the kde session.

5. Pressed Ctrl+Alt+F1 to get gdm login screen.

6. Logged in as a second user to the kde session.

7. Both kde sessions were stuck, but as opposed to previous behaviour I was
able to Ctrl+Alt+Backspace both sessions (maybe because of previous steps I did
not use before).

8. After turning down second session got previously attached kernel trace.

Hi,

I've got the same issue with 4.4 (kernel) not with 4.1.15 when screensaver fire

I got the same problem here with randomly occurring freezes (only mouse pointer
can be moved but I can still ssh into it).

Environment:
- Debian Jessie
- newest backports kernel (which is 4.7.2 currently, it also happened with
4.6*)
- Dual monitor setup with 8800 GTS 320MB

Logs will be attached from dmesg and Xorg.0.log

I think I faced this exactly same crash today on Slackware 14.2 x86 system.

Chromium was loading some page while whole X freezes. i was able to SSH in to
the system but only restart really fixed the system.

OS info :
Slackware 14.2

kernel : 4.4.14 #2 SMP Fri Jun 24 13:38:27 CDT 2016 x86_64 Intel(R) Core(TM)2
Quad CPUQ6600  @ 2.40GHz GenuineIntel GNU/Linux

GPU: 01:00.0 VGA compatible controller: NVIDIA Corporation G84GL [Quadro FX

Mesa:
mesa-dri-drivers-11.1.0-2.20151218.fc23.i686


It is the truth the problem arised after mesa or kernel update, not after Xorg
update. I am not sure but I give higher probability to mesa. Kernel updated on
Jan 12-th (to 4.3.3-300 which I was running when problem arised first time),
mesa on Jan 16-th. I am sure I had not this problem before Jan 12-th. I am not
sure whether I had it between Jan 12-th and Jan 16-th.
