Is irq 18 being shared with your wlan device?  Is it USB which stops 
working after this message, or does it take the whole machine out?  Does 
it work if you disable USB (unload the module, or boot with nousb)?
Konrad, how is this supposed to work?  Is there supposed to be a driver 
in dom0 which mops up "spurious" interrupts being handled in another domain?

Hm, yeah, it seems to work sometimes and not others.  I'm not sure why.  
Is ACPI_PROCESSOR(_XEN) =y or =m in your .config?
