IEEE1394 cdwriter not recognized with 2.4.21(-ben2)

[Gaudenz Steinlin <gaudenz@soziologie.ch>]

Hi

I have a "SmartDisk FireWire CD-R/W Drive" (the kernel reports it as
TEAC CD-W28E) which works with kernel 2.4.19 (debian package). With
kernels 2.4.21 (debian) and 2.4.21-ben2 it does no longer get
recognized.
I modprobe ohci1394 and sbp2, then the drive led's flash and the drive
spins up, but the scsi subsystem does not recognise a drive. I'm not
sure, but I think the IEE1394 bus recognises the drive, because there
are some kernel messages when i plug and unplug the device. 

Is this a general problem with the sbp2 or did I do something wrong? How
can I help debugging this?
