I saw it only ones. Just after kernel upgrade from 2.6.38-rc7 to 2.6.38-rc8. I
couldn't reproduce it.

kernel: 2.6.38
xorg-server: 1.9.4

Right now I use 2.6.38.

Very odd. I noticed that my kernel was compiled without debugging, so I decided
to recompile with debugging enabled to get useful output for you guys. The
strange thing is that with debugging enabled, my kernel can now boot properly

Is it still crashing on newer kernel? I think we fixed it in 2.6.38.5 /
2.6.39-rc5.

(Logs are from 2.6.38 / 2.6.38-rc8 and in both oops triggered on address which
had high word set to 0xffffffff. Considering that between 2.6.38-rc7 and
2.6.38.5 we had a memory corruption bug which could overwrite one word with
0xffffffff, it's quite possible it's the same bug...)
