This smells even more of hardware problems then.  Did you change
anything recently besides your kernel?  And does the system still
reliably run with the older kernel?  

If you have a second Linux computer, you can setup a newconsole to
hopefully capture and then post more details about your system when it
boots and crashes.

I'd personally pull any extra disks, re-seat memory, turn down the
systems settings in the BIOS to very conservative numbers, etc.  No
overclocking at all.  

Also, try removing all but one memory module and seeing if that helps.
