3.12-rc2 Xorg crash when running glxgears

How to replicate:
- booting and doing random desktop stuff

- 1st errors in log: TRAP_TPDMA_2D
thats "normal"/possibly dangerous too:
occured with playing video: mplayer -vo xv -ao sdl 
mplayer: MPlayer svn r34540 (Ubuntu), built with gcc-4.7 (C) 2000-2012 MPlayer
Team


later Crash in log:
- open glxgears on 1st virtual desktop
- switch to 4th virtual desktop 
- open rdesktop program
- xorg is nonresponsive - try keyboard shortcuts to change desktop (dont work)
- wait until Xorg is restarted 

System:
-Linux Mint 15 (Ubuntu 13.04)
-NVAA (Geforce 8200) onboard (Jetway JNC62K)
-dual monitor setup

-Kernel 3.12-rc2

The attached dmesg contains several error messages that are missing from 68037
or are added compared to 69387.
It could be the same "bug"/"bugs" that are described in
68037.
Accel. Video often freeze, stability is increased when playing with x11(without
overlay) in vlc or mplayer. But that might be subjective.

Does posting the card [1] resolve this and/or any of your other bugs ?

Cheers,
Emil

[1] Try either one of the below two
* via the kernel command line - append nouveau.config=NvForcePost=1
* s2ram before running any test - mplayer/glxgears

--- Comment #3 from dirkneukirchen at web.de ---
I enabled posting via kernel cmdline.

cat /proc/cmdline:

BOOT_IMAGE=/vmlinuz-3.12.0 root=UUID=c52e229d-be9c-4d85-b262-5085459dc2d9 ro
rootflags=subvol=@ sysrq_always_enabled ignore_loglevel debug log_buf_len=5M
nouveau.config=NvMSI=0 nouveau.config=NvForcePost=1 sysrq_always_enabled


The crash still occurs:
- LXDE running glxgears
- XFCE running glxgears

Running on KDE : running glxgears "freezes" / makes the Desktop very
slow but
it does not crash Xorg there.

System:
-Linux Mint 15 (Ubuntu 13.04)
-NVAA (Geforce 8200) onboard (Jetway JNC62K)
-dual monitor setup (HDMI+VGA)

-Kernel 3.12.0

Steps to replicate this time:
- Login to desktop (XFCE, dual screen)
- in open terminal window : run glxgears
- switch to other virtual desktop
- Xorg hangs, crash (login screen reappers)

--- Comment #6 from Pierre Moreau <pierre.morrow at free.fr> ---
There was some patches specifically for NVAA/AC cards that went into kernel
3.19. They solve a different issue, but it would still be worth to test it - a
lot of other patches were merged since 3.13, which might also help with it.
