2.0.33 Oops

While admittedly the hard drive was relatively thrashed by 'hdparm -c1
-m16', the kernel shouldn't oops. The result of a scandisk on the hard
drive resulted in a dir00001/ directory which the following oops shows an
'ls' on that directory. (Any access will work, not just ls.) hda1 is a
UMSDOS partition on a Windows 95 drive. Lesson here being don't tinker with
hard drive settings and keep over reset until you know they work. On the
upside, I have 30 megs more of disk space free that I still haven't figured
out what I lost so it must not be important. :)
