So at least you know that ohci0 is the likely source of the storm.
OTOH, it can also be one of the devices that didn't get a driver.  I
don't know off hand the options to have debugging information in the
acpi irq routing code, but one thing that could help is the dmesg(1)
output of GENERIC.MP, for a start.  I'll look at those options later,
or maybe Christos will notice your mail and tell you :-)
