>Description:
I'm running 8.2-STABLE on Dell E6520. The same symptoms are for 9.0-BETA3.

Dmesg is full of following messages when firewire port is enabled in BIOS,
I was also unable to get working dcons console from external machine using
firewire cable. Cable is for sure fine and other machine is also fine
(used to debug other configurations).

firewire0: 1 nodes, maxhop <= 0 cable IRM irm(0)  (me) 
firewire0: bus manager 0 
fwohci0: too many cycles lost, no cycle master present?
fwohci0: fwohci_intr_core: BUS reset
fwohci0: phy int
fwohci0: fwohci_intr_core: node_id=0x00000000, SelfID Count=65, CYCLEMASTER mode
firewire0: 1 nodes, maxhop <= 0 cable IRM irm(0)  (me) 
firewire0: bus manager 0 
fwohci0: too many cycles lost, no cycle master present?

This laptop is using something called O2 Firewire + SD Card controller.
SD Card seems to be working correctly.

>How-To-Repeat:
Boot with firewire (1394) enabled in BIOS (default is of course enabled).
>Fix:
