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.
