Ok, so no IRQ declared for the RTC.  We have IRQ 8 for both rtc and
hpet, which most likely is the root cause for the issue.  You can try
simply dropping the line for testing.  I'll try to come up with
something more clever as the hpet can be disabled in which case we
should keep irq8 assigned to rtc.

cheers,
