I am trying to use a DVD burner in an external ieee-1394 enclosure.
Sadly, trying to scan the bus with either 2.4.42 or 2.4.44 and the
patches from current Linus BK tree fails in the same fashion.
The BUG happens regardless of the presence or absence of a device on the
bus in question:

On the plus side, the external enclosure is identified and returns valid
identifying information:
ieee1394: Host added: Node[01:1023] GUID[00061b0010003321] [Linux OHCI-1394]
Rescanning the SCSI bus or using scsi-add to try and have the device
identified correctly fails, however, and I cannot access the hardware.
Rebuilding with excessive debugging output, rebooting and /not/ running
gscanbus gives me no BUG, but no joy with the device either: it still is
not detected.
The following is the log from powering down and then up the device:

actually masturbate.
