Got this on boot. Looks like another locking bug in firewire:

ACPI: PCI Interrupt 0000:03:03.0[A] -> GSI 20 (level, low) -> IRQ 20
ohci1394: fw-host0: OHCI-1394 1.1 (PCI): IRQ=[20]  MMIO=[ec024000-ec0247ff]  Max Packet=[2048]  IR/IT contexts=[4/8]
stopped custom tracer.

other info that might help us debug this:
