For the most part it does.

tallison@isengard:~$ lsmod | grep 1394
raw1394 25580 4
ohci1394 30388 0
ieee1394 88376 2 raw1394,ohci1394

During boot I get:
Apr 19 19:25:47 localhost kernel: ohci1394: $Rev: 1313 $ Ben Collins
<bcollins@xxxxxxxxxx>
Apr 19 19:25:47 localhost kernel: ohci1394: fw-host0: Unexpected PCI
resource length of 1000!
Apr 19 19:25:47 localhost kernel: ohci1394: fw-host0: OHCI-1394 1.0
(PCI): IRQ=[193] MMIO=[e8000000-e80007ff] Max Packet=[2048]

But I have to manually modprobe raw1394:

Apr 19 19:26:44 localhost kernel: ieee1394: raw1394: /dev/raw1394 device
initialized


However, I continuously get a message that 'no camera exists' when I try
to grab anything. Yes, the camera is on. No the camera doesn't seem to
think there is much to talk to either. Once I get a 'DV-IN' message on
the camera.

Sounds like a bad cable?
Might be, I haven't any way of knowing, the cable is about 2 hours old.

But digging around I found mention of something called gscanbus as a
tool to identify what's on my system. It generally doesn't do much
useful. In fact once started, it doesn't really appear to do anything
at all. Then after about 3 minutes my entire system freezes and I have
to pull the plug and restart the system. keyboard, mouse, network,
everything.

Because of this, I'm not entirely certain it's just a cable.

I'm currently running 2.6.15-1-486 kernel

Any suggestions? I'm not sure what the next step is other than to get
an RMA and never try firewire again.





Sounds about like the same problem I have. I found the solution on some list
somewhere ( Can't remember if it was here or not). It's a weird solution, but
works for me.

I have to do a "rmmod iee1394" , then it just works....

Strange, huh? Hope it's the same issue for you....
