Occurred while trying to mount a CD-ROM as it was being inserted into
the drive.. Got the drive not ready twice, followed by detected disk
change, and the following:

Unable to handle kernel paging request at virtual address c101615f
current->tss.cr3 = 007dc000, r3 = 007dc000
*pde = 0009e067

Tracing by hand, as ksyoops segfaults, and klogd couldn't handle the
new /Symbol.map format:

[<00125c49>] : get_fs_type
[<00125fe6>] : read_super
[<0101615f>] : <out of range: isofs module?>

I think I've seen this one before but forgot to save it.. seems to
happen when the mount happens and the drive is still checking the
CDROM.
