Was there an allocation failure earlier in the log?

Might be this nouveau bug (linux-next at the time was 3.8 now):
https://bugs.freedesktop.org/show_bug.cgi?id=58087

I think this was fixed but neither bug report has a cross reference :(

The original report is here:
https://bugzilla.kernel.org/show_bug.cgi?id=51291

Pekka,
Can you please re-assign the bugzilla #51291 above to DRI? Thanks.
