Watchdog Reset & other issues

Hello all,

I have a SS20.  I had been running Debian Sid, at which time I had it up for
extended durations with few problems.

I recently got an 8 meg VSIMM (never opened, still in the sun box :) ).  
I figured I'd try Aurora since I've used Red Hat is the past & liked the new
desktop.

1.  I noticed that the performance seems to be a little anemic, but I chalk
this up to the new 2.4 kernel on a hypersparc.  
     I've heard comments that I should step back into 2.2 if it's an issue
(can someone give me an option?).

2.  The other day I came home to a white screen with an open boot prompt
saying "Watchdog Reset".  
     Is this a kernel issue also?  It didn't happen on 2.2, but I didn't
have the new VSIMM then either.

What is the watchdog reset exactly?  Is it likely to continue to happen?
Any thoughts are appreciated.

Thanks, Joel.
