Kernel lockups - how do I troubleshoot?

[Jor-el <jorel@trillian.megadodo.umb>]

Hi,

	I am running testing / unstable on a dual CPU Tyan Tiger 100
motherboard with 2.4.15pre1 . My machine has locked up on me twice in the
past week leaving no clues in the syslog or anywhere else. At the point
where it locked up, the screen was in power saving mode and couldnt be
brought back live by using the keyboard or mouse. I had to use the reset
to get it to reboot.

	I'd greatly appreciate it if anyone could either tell me how to or
point me to any info which will atleast allow me to gather info on the
crash, so that I can post it to linux-kernel.

Thanks,
Jor-el
