There was a non-fatal oops in copy_thread some minutes ago:
Unable to handle kernel NULL pointer dereference at virtual address c0000000
current->tss.cr3 = 00101000,

The oops happened when I was reading a message in a pine. gcc was
rebuilding the gnome-0.12 rpm in the background. X was not running
as I was working in the console. It seems gpm died during the oops
and it even won't restart.
If there is anything I can do to help tracking down this bug please
mail me.
