I expect it's heat-related, too.

Does an XL have a button-driven LCD display panel like an L does?  Does it
say inything interesting about the failure, or about the system events?

Is the thing generally running hot?  Commanding "/usr/etc/sysctlrd -p" will
tell you some things about heat in the machine.

Anything in the logs?
