Assuming this isn't a hardware isse...
Getting a stack backtrace and threadlist dump would be helpful in
figuring what's causing your system to hang. Try booting under kadb
with:
        # reboot 'kadb -D kernel/sparcv9/unix'

When the system hangs, do a "stop-a" (or equivalent) to drop down into
the kernel debugger. At the kadb prompt get a stacktrace with "$c".
You can dump the threadlist with "$<threadlist", and take a crash dump
with "$<systemdump". I think Sun support would find this data helpful.

Hope this helps,
-Eric
