=================
ORIGINAL QUESTION
=================

I have a Sparc 10 running Solaris 2.6 that kept crashing to the prom
level (init 0). There is NO error in the system log. The only
indication is:

fat
Watchdog Reset

on the console. So far I can't seem to find info on Watchdog Reset
on any reference manual. Does anybody knows what this mean and how
to correct the problem?

===========
SOLUTION(s)
===========

Many thanks to all those have replied. I apologize if I missed
anyone.

Watchdog reset is hardware trap that sent an interrupt to the CPU
to prevent further damage when there is some kind of hardware
problem. Hardware problems that frequently occurred are:

1. Over heating.
2. Memory error.

**NOTE**

1. Watchdog can be disabled by setting "watchdog-reset" to false
   at your eeprom. This can be a "doable" solution but personally
   I would not recommend this.

2. Perform diagnose at the prom level by running ctrace, .registers,
   .psr, or .locals.

Thanks,
