>Description:
Machine is very sluggish, one core is occupied processing interrupts.

CPU0 states:  0.0% user,  0.0% nice,  0.0% system, 85.8% interrupt, 14.2% idle
CPU1 states:  0.0% user,  0.0% nice,  0.0% system,  0.0% interrupt,  100% idle

Checking vmstat -i right after boot, no USB devices connected:

interrupt         total  rate
TLB shootdown      1060    11
cpu0 timer         8975    97
ioapic0 pin 19     2209    24
ioapic0 pin 18  7074499 76896
ioapic0 pin 17       11     0
ioapic0 pin 16      225     2
msix1 vec 0         243     2
Total           7087222 77035

pin 18 is shared by ohci and radondrm. Eliminating radeon makes no
difference, disabling ohci makes the interrupts go away.

While the interrupt storm is going on, the machine hangs on reboot.
Reboot -n usually works. Unclear how these are related.

A OHCI keyboard is not detected on hotplug (duh).

This is not a new issue, just reporting it in case someone has a good
idea what to try next.

The com0 port isn't physically present, nor could I spot any solder pads,
making debugging this thing a real pita.
