Description of problem:

AMDFX-55
2GB ram (memtest86+ verified OK)
Nforce4 motherboard

I got a kernel panic during install of rawhide March 9th 2006, I did another
install that went OK. I setup netconsole/netdump and then ran the "stress"
program to put memory, cpu, and I/O load on the box. After several hours this
showed up:

slab: Internal list corruption detected in cache 'journal_head'(59), slabp
f0fb7000(2097211). Hexdump:
