Thanks, I'll bcc this response to the bug, let's continue discussion 
there.

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' 
(appearing before the prompt) after it completes execution of 
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.

In a failure case, how long does it take between you typing 'boot' and
"watchdog reset" message being displayed? This doc

http://docs.oracle.com/cd/E19102-01/n240.srvr/817-5481-11/understanding_wdtimer.html

appears to suggest that stuck watchdog would initiate a XIR after 60 
seconds by default, is it consistent with what you see? What are the 
values of various variables mentioned there on your system(s)? Does 
increasing the timeout help?

I really can't come up with any reason why it would work for Squeeze 
but not other releases, so testing all suspect SILO versions on the 
same machine would be an interesting experiment.

That only works when you have repositories containing older/newer 
packages listed in your /etc/apt/source.list. Simply adding them 
(without configuring apt pinning appropriately) may mess up too many 
things, so the simplest way is probably to just download older SILO 
debs (should be available on archive.debian.org) and install them 
using dpkg -i.
