Usually system crashes afterwards and only blacklisting nouveau module helps.

Works with 2.6.33 (and probably 2.6.34-rc, let me know if you need more info here).
Comment 1 Ben Skeggs 2010-05-19 18:15:30 EDT
The fix for the memory corruption bug is in the F13 kernel, and has been sent upstream for 2.6.35-rc1 also.  It'll make it into rawhide when they do an update.
Comment 2 Ben Skeggs 2010-06-06 19:25:32 EDT
This bug should be resolved now, 2.6.35 is in rawhide.  Closing.
