>Description:
Watchdog reset happens on my SS20 with cgsix as follows.
1. Login console (not necesarily as root),
2. cat error.dat
3. PROM monitor appears...
  Watchdog Reset
  Type help for more information
  ok 

"error.dat" is here.
-----------------------
begin 644 error.dat
M9@`P,38```#L`!0("&YE='=O<FMS`#`Q-@```/X`%`@(<V5C=7)I='D`,#$V
M````_0`,"`-R<&,`````[@`8"`UN<W-W:71C:"YC;VYF`#`Q````[P`4"`AN
3='`N8V]N9@`P,38```#P`!0("PUN
`
end
-----------------------
Watchdog reset happens when some kind of data sequence like
"error.dat" is written to "screen", so doesn't happen
by login via ssh.  But I don't know what happens by serial
console login.

I found this problem when I did
$cat /etc
in mistake for
$cat /etc/fstab
so, please try cat /etc too if cat error.dat cause nothing.

Thank you.

>How-To-Repeat:
Login console, and 
$ cat error.dat

"error.dat" is here.
-----------------------
begin 644 error.dat
M9@`P,38```#L`!0("&YE='=O<FMS`#`Q-@```/X`%`@(<V5C=7)I='D`,#$V
M````_0`,"`-R<&,`````[@`8"`UN<W-W:71C:"YC;VYF`#`Q````[P`4"`AN
3='`N8V]N9@`P,38```#P`!0("PUN

end

>Fix:
I don't know.
