If you configure the Xen serial console "com1=115200,8n1" you
should get a crash dump. There are some very rare circumstances
where this doesn't happen, but I suspect that you'll get an Oops
from domain 0, then Xen saying "domain 0 exited, rebooting
machine". Hopefully the crash dump will tell us why dom0 exited. 

BTW: Are you using one of our pre-compiled xen and xenlinux
images? We'll need the vmlinux-syms file to interpret the crash
dump.

The watchdog will detect and generate a crash dump if certain
types of deadlock occur. It's unlikely to help debug this
particular problem.

I've just ssh'ed into dom0 for dom1 just fine. I haven't seen a
bug for quite sometime, and I've been thrashing the system pretty
hard.
