Definitely only have one 'console=' option on DOM0's command line. It
may be that some infomration is only getting output to a device that
you are not looking at. It's very unlikely that the machine will
reboot with no visible error message at all.

Are you viewing DOM0 booting over serial line or on the VGA console?
If the former, then specify console=ttyS0 on DOM0's command line. If
the latter then specify console=tty0.

Not that for all other domains you should always specify console=tty0.
