PROBLEM: hangs early when ssh'ing in

[Andreas Loong]

SPARC SPURIOUS HANG

[1.] SPARC Watchdog reset

[2.] at various times when I SSH into the system, I get a watchdog reset and
the machine drops down to the prom. This seems to happen most often when
the machine just has booted. since it dies immediately, I have no output
from the console. Once the machine has been up for a while, this doesn't
seem to happen at all.

[X.] Other notes, patches, fixes, workarounds:
Seems to only happen just after it has booted. I'm rather new to linux and
more heavy on the solaris side, but I would like to help solving these
issues - only I don't know exactly how. seems like debian woody is shipped
with gcc 2.95.4, not sure if this is relevant or not.

I have some time on my hands and I've notice a couple of weird things that I
will report aswell, as long as someone could guide me through the process.
