Kernel Lockup - Was: Probably 2.4 kernel or AIC7xxx module trouble

[Jim Gifford]

I wrote a small script last night to check my problem.

#!/bin/sh
rm /root/ps.dat
while true; do
  # Date the file, or you could as well use the file's date field.
  date > /root/ps.dat
  echo "====" >> /root/ps.dat
  # Have a snipset of what's running on the machine.
  ps aux >> /root/ps.dat
  # To be sure we didn't crash while ps'ing
  echo "====" >> /root/ps.dat
  # To pevent from FS corruption
  sync
  # Have a little sleep... |-O
  sleep 1
done

The wierd part is that the system didn't lock up, last night like it usually
does.

I also had vmstat -i run all night also, to help locate the problem.

Here is the output of both files and the loadaverage
