A PL-3507 based CD-RW always had the following bug.  The new firewire driver stack is confirmed to be working well with this CD-RW.  The old drivers show this bug especially --- but not only --- if there is a TI PHY in the mix (TI based card or TI based hub).

The Sony PCGA-CRWD1 bundled with the Sony Vaio PCG-VX71P laptop shows the bug as a regression from 2.6.24 (Ubuntu 8.04) to 2.6.27 (Ubuntu 8.10).  The new firewire drivers have not yet been tested by the PCG-VX71P owner.  The Vaio laptop has a TI link and PHY; the SBP-2 chip in the PCGA-CRWD1 is not known.

A successful workaround with both CD-RWs is to
  - unload the ohci1394 if already present,
  - plug in/ power on the CD-RW,
  - load ohci1394.

Another "workaround" at least with the PL-3507 based CD-RW is to use the new firewire drivers instead of the classic ieee1394 drivers.

I categorize this bug as blocker of bug 10046 although I will look into fixing it as time permits.

I categorize it as a regression even though it is only a regression with Sony PCGA-CRWD1 but not with the PL-3507 based CD-RW.
