Comment 37 for bug 601530

Re-closing as there's not been further information from the original reporter.

The error message is a generic one that is written whenever the GPU is locked up. Just because you see this error message does not mean you have the same root bug as someone else.

In general, upgrading your kernel is the proper way to solve the bug. If you want to see a fix in lucid, you'd need to do a bisection search to find the relevant patch to be backported, but I'll leave that to the kernel team to explain. :-)

Fwiw, in Precise the vast bulk of these kinds of freezes are gone (there's still a few but they are much less common and more esoteric than in older kernels.)
