Ultra 10 Panic - lockup

[cflec...@altsoftware.com]

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.

Based on my (Solaris-based, not FreeBSD) knowledge of U10 issues,
RED state exceptions are an indication of a broken CPU.
