strange scsi/CAM related dmesg output

hi there. running HEAD, amd64 and r208806 i get this dmesg output
which doesn't look right:

ada0 at ahcich2 bus 0 scbus3 target 0 lun 0
ada0: <SAMSUNG SP2504C VT100-50> ATA-7 SATA 2.x device
ada0: 300.000MB/s transferscd0 at ata2 bus 0 scbus2 target 0 lun 0
cd0: <HL-DT-ST DVDRAM GSA-H10N JL12> Removable CD-ROM SCSI-0 device
cd0: 33.300MB/s transfers (UDMA2, ATAPI 12bytes, PIO 65534bytes)
cd0: cd present [1944656 x 2048 byte records]
 (SATA 2.x, UDMA6, PIO 8192bytes)
ada0: Command Queueing enabled
ada0: 238474MB (488395055 512 byte sectors: 16H 63S/T 16383C)


my kernel contains:

options         SC_HISTORY_SIZE=1000
options         MSGBUF_SIZE=65536
options         PRINTF_BUFR_SIZE=128

might this be caused by one of these lines?

cheers.
