Hi,
just had a few oopses on my production machine that serves a few
webservers and email for some clients. Because it's not too much loaded
I had the rc5des cracker running also. First oops was from rc5des (no
relevant data in there) then I got the following oops a few times.

(Somebody trying to smash my stack?)

Unable to handle kernel paging request at virtual address cc06517c
current->tss.cr3 = 00101000,
*pde = 00000000
