          Priority: medium
            Bug ID: 72939
          Assignee: nouveau at lists.freedesktop.org
           Summary: [nv96] Freespace 2 open crashes
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: madman2003 at gmail.com
          Hardware: Other
            Status: NEW
           Version: git
         Component: Drivers/DRI/nouveau
           Product: Mesa

This has been an issue for much longer, it looks to be a memory related
problem. Textures are corrupted and after a little while the card hangs. I've
confirmed with the binary blob that the hardware works fine.

The errors that i got were:
Dec 20 22:12:41 madman kernel: [   66.490366] nouveau E[  PGRAPH][0000:01:00.0]

This was with a 3.13-rc4 kernel and a very recent git mesa (also tried mesa
9.25, had the same problem).

In general i don't think any graphic intensive runs for a very long time. It's
just that this one is very easy to make crash.

My question is, what can i do to narrow this down? Keep in mind that this has
been going on for more than 6 months probably (maybe even a year) and I can't
take my kernel too far back into the past (because my system is compiled
against modern linux headers).
