It also happens with _pristine_ 2.4.18pre2. I ran

cat /dev/hde > /dev/null& cat /dev/hdg > /dev/null& ping -f -s 64000 box2

in single user mode. (hde and hdg are Samsung 80GB disks on HPT370, eth0 is
3c905). After just few seconds I got the following oops:

Which is pretty similar to the 2.2.20 oopses (here's one:)

This is with the bios settings we thought stable. 

Any ideas?
