Quite interesting, it's basically the same oops I've got about two
weeks ago (except my process was tar), and I sent it to the list on June,
22. I was running UP, though...
Here are my oops:
Unable to handle kernel NULL pointer dereference at virtual address 00000001
current->tss.cr3 = 07466000, %cr3 = 07466000
*pde = 00000000
