Computer Freezes - how to find out what happened?
I have just built myself a new computer (i5 2500 with Intel Motherboard)
and am getting a situation where the user interface freezes every so often.
I suspect it is more than just X freezing, because when that has
happened in the past I can ssh into the machine console and still do
things. In this new circumstance I can't.
However I suspect its not a completely solid freeze of the hardware,
because if I push the reset button on the computer, after a delay of
maybe 15 or 20 seconds the screen goes blank and then it successfully
reboots itself. During that reboot sequence there is no indication that
the previous shutdown was not successful. I.E what appears to be the
case is that the reset kicks init into a successful shutdown and reboot.
The only indication I can find in the log of anything strange is the
Init "co" respawning too fast messages.
Here is syslog over the period of the reboot (apologies for mail wordwrap).

Any ideas on how to debug this further.
