I had a showstopper yesterday. I ran e2defrag in single user and whilst
e2defrag was relocating maps this hit me resulting in an worthless /usr
- I will get that damn DAT drive!

I myself suspect bad memory (which I took out for now to be sure) but
could someone (Linus?) look at the oops and see if it looks like a
hardware glitch (bit-flip or so) or could it be a real problem with the
kernel?

I wrote the oops down by hand. I can't give you disassembly lists as
vmlinux was lost with everything else in /usr.
