acd0: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00 sks=0x40 0x00 0x01

avl> Kernel from March works normally...

I get a similar message when trying to load "atapicam",
on an Apr 20th kernel+world:

  # kldload atapicam
  acd0: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00 sks=0x48 0x00 0x01

No /dev/cd0 entry is created.

This device is a:

  acd0: DVDR <PIONEER DVD-RW DVR-K16RS/1.35> at ata0-slave UDMA33

Apart from this ATAPICAM error, trying to burn CDs using
burncd using the ATA device "/dev/acd0" also misbehaves,
with an "I/O error" encountered a few seconds into each
file being transferred to CD.

Mounting CDs using the ATA device continues to work ok.

IIRC, the 200702 snapshot of FreeBSD -current had worked
without hitches on this hardware.
