Gotta love the list...
Thanks to jasonn@nabaus.com.au (Jason Noorman) who tipped me off
that older rev (pre rev08) motherboards have problems:
When we first recieved the first batch on U2170 we had a similar
problem.
After about a month of research on our behalf, ringing sun's component
suppliers etc, the problem was isolated to the motherboards.
Apparently we had rev 6 motherboard that contains a small fault in the
system would reset due to electronic noise, originally sun pointed the
finger at the power supplies when it was board design itself.
Have your board checked to make sure it is a rev 8 or higher.
-- Mine was rev07. I have a new motherboard on its way from Sun.Thanks also to:
