The way that I arrived at this situation was I had a pcmcia flash card
in mounted as /mnt/pccard and then I ejected it without unmounting the
file system. Suspended my computer and went away. Hours later I turned
on my laptop and then re-inserted the card. The modules didn't load
and so I tried to su to root and restart the pcmcia services. Every
time I did a "su -" it core dumped. I rebooted and checked
/var/log/messages and it had a bunch of oopses. It appeared to have
one for every time I tried to su.
I looked in oops.txt and tried to gather the information needed but I
can't seem to find ksymoops on my computer (where do I get it?). So
what I did was sort ksyms and try to match up the addresses to the
backtrace. Hopefully it is enough. I will be compiling up 2.1.76 right
now to see if the problem persists.
