Since I did some work to find a suitable replacement disk, I also took 
the time to swap the two CPU modules

           SMCC SPARCstation 10/20 UP/MP POST version VRV3.45 (09/11/95)


CPU_#0        HyperSPARC ROSS RT620/RT625         0x00040000 Bytes ECache
CPU_#2        HyperSPARC ROSS RT620/RT625         0x00040000 Bytes ECache

No change in POST....
I did torture it a little in single-processor mode, so that I could run 
on "the other" CPU. No issues.

Then I rebooted MP and this time instead of "Watchdog reset" I see the 
serial console flooded with:

I hope this is super-meaningful for you!
