Well, good news. The patch seems to be worked as you designed.

Compiled the kernel with your patch, rebooted the machine and plugged in
the camcorder to the firewire port. This is what the log said:
May 31 11:06:47 red kernel: [ 924.228439] firewire_ohci: isochronous
cycle inconsistent
May 31 11:06:48 red kernel: [ 924.821383] firewire_core: created device
fw1: GUID 08004601024aca36, S100
May 31 11:06:48 red kernel: [ 924.821396] firewire_core: phy config:
card 0, new root=ffc1, gap_count=5
May 31 11:06:48 red kernel: [ 924.833768] firewire_core: IRM is not
1394a compliant, making local node (ffc0) root.
May 31 11:06:48 red kernel: [ 924.833777] firewire_core: phy config:
card 0, new root=ffc0, gap_count=5


And that is all it said ever after I captured a footage of some seconds.
I used the following command:
$> dvgrab -a -f raw -t video-

Then I switched off the camera, and still there were no messages in the log.

So, what is verdict?

Meanwhile, I will continue using this kernel.

Thanks.
