I am running 2.2.6-BETA and I experienced a spontaneous reboot.  It was
more like a hard reset than a reboot and the video went all to hell,
appeared to CGA or something like that.  I shutdown the computer and
checked that all the boards were seated properly and restarted the
computer and it worked fine.  It was just a single instance -- go
figure. It has benn three days now without any problems.
Cheers,
Frank
