How do I determine the cause of the crash?  When this happens, my system
immediately locks up and stops responding.  There is no OOPS message or
anything else.

Also, is there any better way to trap all the info that alt-sysreq-p
shows me?  Is there other info from other alt-sysreq combos that I ought
to report?

I'd be happy to provide more info, but I need a little guidance.

Thanks,

-Mark
