I just had my system freeze. No response to pings, usb is dead, no idea 
if I'm in db since usb keyboards don't work without disabling pckbdc 
first. In the middle of compiling firefox, downloading an ISO, and using 
rdesktop. I don't ues IPv6 at all or ipf.

I had xosview running, shortly before the system froze, cpu usage 
dropped to less than 40%, and the net download stalled. Not what i'd 
expect while compiling firefox
