Unclean Reboot For No Apparent Reason

[Ben Haysom]

Hi

A while ago I asked about my 5.3 machine which has taken to rebooting
itself during a full portupgrade.Doesn't shut down properly - just
resets.

I was advised to try a few things.

I've done memtest86 from CD, let it do 5 passes and it found no problems.
I unplugged both CDs and the Floppy, and tried it, but still did the same.
cpuburn seems fine.
doing mbmon whilst executing the portupgrade -a command shows the
temperature get to around 42.5 before it resets, but it can vary.

I'm stuck now... any ideas?
