        The serial console says:
(XEN) Domain0 shutdown: rebooting machine.

but nothing happens.... It doesn't respond to ctrl-a at
this time neither.

When the system is running using ctrl-a to get back to xen
works and 'q' followed by 'R' gives following output:
NetBSD/i386 (netxen.syncrontech.com) (console)

I tried also putting "noapic" and "noacpi" to menu.lst but it didn't help.
