FYI:

I'm attaching two OOPSes, see comments below...

ksymoops 0.7c on i586 2.3.99-pre4.alpha3.1. Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.3.99-pre4.alpha3.1/ (default)
     -m /boot/System.map-2.3.99-pre4.alpha3.1 (specified)

OOPS#1: I was playing with firewalling rules / iptables when this one
OOPS#1: occurred...

OOPS#2: I was trying to play a VCD using 'mtvp' when this one occurred,
OOPS#2: I had mounted shm, and it is very possible I did something stupid,
OOPS#2: but here's the oops anyway.
OOPS#2: BTW, what is the correct way of mounting shm?
