AVLAB 1394b-to-IDE 2.5” Drive Kit, INIC-2430F based

A few log lines appear, then the PC *reboots* right away. Happens consistently.
Did not happen with the kernel I used before, 2.6.11.x + up-to-date linux1394.

"cdrdao read-cd ..." and "cdrdao write --simulate ..." work.
No sbp2_check_command or _response is logged during cdrdao's runs.
scsi_host_dev_release is not called when the DVD-RW is disconnected, but
that is another story.

Same again.

I will have a closer look at the silent 3.5" disks right away.
