The only non-standard thing is the ipw drivers (ipw3945-1.2.1).

Have you tried testing a kernel which doesn't have those drivers?
(It'd be a clever little driver to cause that BUG though)

No, happened only one time.

Yup :-) It didn't happen again in the meantime, but anyway. I'll keep
you informed.

Looks like the slab header was corrupted. If this can be reproduced then
you need to enable slub debugging to find the kernel function that
corrupts memory.
Otherwise it could be bad memory?

Yup, I'll try that if it happens again.

Hmm, the box is relatively new, but one never knows. Ah, and it was
after I've resumed the machine from suspend-to-disk, but not right after
the start but some minutes later.
