Can this be responsible for a newly seen 

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

in dmesg? The relevant part of dmesg is:

acd0: CDRW <UJDA750FDVD/CDRW/1.21> at ata1-master UDMA33
acd0: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00 sks=0x40 0x00 0x01
cd0 at ata1 bus 0 target 0 lun 0
cd0: <MATSHITA UJDA750FDVD/CDRW 1.21> Removable CD-ROM SCSI-0 device 
cd0: 33.000MB/s transfers
cd0: Attempt to query device size failed: NOT READY, Medium not present - tray closed

atapicam is compiled into the kernel. I have never seen this
"acd0: FAILURE..." line before...
