Bug 73369

I don't know if this is worth fixing or not, but it is certainly worth documenting.

I hav e abrand new AMD64 machine with a K8V SE motherboard. It's an amazing motherboard with an 800 Mhz system bus, 5 pci slots, a wifi slot, 2 Ultra ATA 133 connectors, 2 serial ATA connectors, 8 USB 2.0 ports, built-in gigabit, and 2 Firewire ports.

I have a bunch of firewire drives. WHen I attach the drives to the motherboard, it gets the bus reset but it usually doesn't create the /dev entries for the drives.

I try resetting the bus with the fwcontrol command. That doesn't work either. Here is what is printed on the console:

fwohci0: Initiate bus reset
fwohci0: BUS reset
fwohci0: node_id=0xc800ffc1, gen=2, CYCLEMASTER mode
firewire0: 2 nodes, maxhop <= 1, cable IRM = 1 (me)
firewire0: bus manager 1 (me)

I plug in a standard Firewire card and it works just fine.

Fix: 

Don't use the on-board firewire.
How-To-Repeat: Buy this motherboard. Or don't.
