  Some short period later it crashed again. I enabled savecore, and got the
stuff below. The machine is a P75 with 32Mb ram. It has a 1.6Gb and a 6Gb
drive. fsck seems to clean some files after each reboot from /var, but
other than that the file systems are sane.
  The machine seems much slower after the most recent reboots, but may
just be the load of email coming in after downtime. It is behind a firewall.

  (I got far more details from the kernel debugger)
