I got this oops this morning with 2.6.9
I have rebooted without the nvidia module and will let you know if it
hapens again.
Let me know if you need more info

So eax (20001045) is page->flags, which is
PG_locked | PG_referenced | PG_active | PG_private, I think.
You might have flipped a bit. Can you run memtest86 on the system overnight?

Ran for 12 hours overnight. Extended tests, no errors.

OK, it's just that it's a pretty common path in the kernel, and if
there was a bug there you'd be very unlucky to be the only one
hitting it. Still, it's possible. Probably the best thing to do is
report it if it happens again.
Oh, what sort of system is it? CPU, how much RAM, etc?
Sorry I can't be of more help.

well he's using the nvidia binary driver... maybe that's interacting
funny....
