Ultra 10 Panic - lockup

[Chris Flecknell]

Can anyone give any insight to this?   The system is an Ultra 10 - 440MHz,
512 Ram.    The system will lockup completely and have this left displayed
on the console.   The system can sometimes stay up for as long as a number
of days, or as short as a few minutes.  I *think* it's most likely hardware
related, but am not sure how I can find out.  I have gone through the Boot
tests and it's never found a problem.

Any help with this would be greatly appreciated.
