random reboots.

["Michael Shutes" <mshutes@metcon.com>]

i have a amd k6-2 machine with 128 megs of ram running obsd 2.5 generic.
the display is a mainboard SiS 630 chipset.  i am running XFree86 3.3.5.
90% of the time everything works fine.  the other 10% of the time the
machine randomly reboots, or locks up solid.  this only happens when x is
running.  i have run the machine weeks on end under high load without x and
never had a problem.

suggestions?

thank you,
