Sorry, small update:
This happens with 2.3.32 as well, but not with 2.3.31. I did not notice
this at first because the bug only shows up when I write CDs in MODE 2
(-mode2, -cdi or -xa2).
Could the problem be related to the sectorsize not being a multiple of
512? I've noticed that the scsi driver sometimes computes the number of
512 byte sectors as (bytes >> 9), which is not correct in this case.

Yes, everything except my scsi cd roms keep working.

OK. Here is the full output of the last scsi command that comes through:
