OK, Thanks for the update. I didn't explain how I got the kernel oops so
to make sure the bug got squashed, here's how I triggered the oops using
ubuntu 7.10:

echo "/mnt/bin/bash" > readlist
mkdir -p /cow
mount -t tmpfs tmpfs /cow
mount -t unionfs -o dirs=/cow=rw;/=ro unionfs /mnt
readahead-list readlist

When ubuntu git repos for kernel and module source get upgraded will that be
for "gutsy gibbon" or "hardy heron?"
