Looking at the output you see, I have doubts that it has anything to
do with SILO though. SILO prints letters 'S', 'I', 'L' and 'O'

different parts of first-stage loader. As you can see in the code
(first/first.S), printing 'S' is the first thing first-stage loader
does upon startup. The fact that it is not seen in the console output
suggests that even first-stage loader never got to run. The line
Boot device: /pci@1f,0/pci@1/scsi@8/disk@0,0:a File and args:
which is normally printed by OBP before control is passed to SILO does
not appear in the watchdog-reset case either, which, again, is a
strong sign that failure happens before SILO has a chance to run.
This is something to do with the type of disc being used, i.e. the exact
firmware version or similar, rather than the Debian release or the
version of SILO etc.
I'm using non-Sun SCA discs, badged Compaq but apparently WD. Some work
OK while others- nominally the same but with visibly different PCB- fail
the first boot.
This might still be specific to OBP in a Netra T1, both types of disc
boot first time in an Ultra-1. It affects Lenny, Squeeze and Wheezy, and
possibly other OSes.
