>Description:
	Since roughly when I started running 1.3E+UVM on my NEC Versa 2405 
laptop, I have seen several spontaneous reboots. Ths syestem does not appear 
to panic or dump, but acts as if a reset button has been pressed (the machine
does not actually posess such a button). It happens when the machine is 
approximately idle but has been used recently. The system is generally running
an X server, several X applications (xterm and emacs), and a variety of daemons
including dhclient, apmd, named, xntpd, and afsd. The X aperature driver and
AFS LKMs are both loaded and in use.

>How-To-Repeat:
	Not clear, but I include my kernel config file and autoconfiguration
output for information.
