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: no locks held by idle/0.
