GPU lockup [Lucid]

[Leo Howell]

I'm filing this separately from bug #537080, since the comments there indicate the problem goes away with the nvidia drivers. This is not the case for me. Also, my Xorg.log has a callstack at the end.

When using my computer, occasionally X will freeze apart from the mouse, using 100% CPU. It can happen whatever I'm doing, but most often while using thunderbird.

I usually hit this problem once or twice a day, but so far I haven't been able to reproduce it on demand.

[mi] EQ overflowing. The server is probably stuck in an infinite loop.

Does a newer nvidia driver solve it?
