    I'm also seeing this with a combined DVD-reader/CD writer on -CURRENT. I
    haven't seen this with my NEC DVD writer, but granted - I don't burn too many
    CD's on that one.
    It only seems to happen when writing and then fixating in one command. If you
    then fixate the CD afterwards, all is well, ie:
    burncd -f /dev/acd0c fixate

    I also haven't seen this with an AOPEN CRW5224, in PIO4 mode, on -STABLE.
    Media varies, but mostly I use Nashua disks.
