I tried to import video from a Sony mini-DV camcorder but the camera doesn't seem to be recognize by the HP 8440p. I tried with both new and old firewire stacks without success.

After enabling debug mode, my kernel logs are full of these messages:

The bus seems to get reseted in loop until I disconnect the camcorder.

I successfully could import the video using a Lenovo T61p which also runs Maverick (and probably the same kernel too).

From the HP 8440p:

Bug 550010 seems to be a bit similar. Thank you.
