I get very similar symptoms, corrupted screen (Ubuntu login screen constantly attempts to redraw itself with widgets in the wrong place) and missing mouse pointer after login on my MacBookPro7,1 Nvidia 320M:

VM: trapped write at 0x00523b0000 on ch 2 [0x000007f9] PGRAPHG/PROP/DST2D reason: VRAM_LIMIT
...


there are *plenty* of those. Kernel is 3.5.0-13 #14-Ubuntu SMP

The very first *error* in dmesg that I can see is
 PGRAPH - TRAP_TEXTURE - TP0: Unhandled ustatus 0x000000003

possible fix

Does this patch happen to fix your first issue by any chance?

Sebastian: your bug looks completely different. Please file new bug report as described here: http://nouveau.freedesktop.org/wiki/Bugs
Comment 3 Alin M Elena 2012-09-12 19:18:25 UTC 
Hi Marcin,


I still have all the issues...  with the patch applied and today's master on 3.6.0rc5.

though it seems I donot get the random crashes anymore.

regards,
Alin
Comment 4 Ilia Mirkin 2013-08-24 02:05:51 UTC 
Alin, please re-test with the latest kernel. If you're still having issues, please supply a complete dmesg form that kernel, as well as the Xorg.0.log. Also you could use a mesa upgrade (to at least 9.1).
Comment 5 Ilia Mirkin 2013-09-26 23:12:08 UTC 
No response to re-test request in over a month. Closing as invalid.

I'm not sure that reopening a bug, that you've did not report nor respond previously is a reasonable thing to do.

With that said, noone can imagine what the issue on your system could be considering the isolated snippet from dmesg.
For more info what is required take a look in here [1] and open a separate bug report.

Thanks
Emil

FWIW The *class 0x8697 mthd 0x0e0{4,8} data 0x* messages should not cause any issues.
