acd0: WARNING - REQUEST_SENSE read data overrun 18>0

Hello,

already for some time it seems I'm unable to mount regular CD's
(although, could be that not all?), and I get messages like this:
acd0: WARNING - REQUEST_SENSE read data overrun 18>0

after a while system hangs (if I won't eject cd ;)
I'm using yesterdays -current with atapicam, it's T40 with 
acd0: CDRW <TOSHIBA DVD-ROM SD-R9012> at ata1-master UDMA33

Any ideas? (of course, I'll try disabling atapicam, but that's not very
good option ;)
BTW, cd burning with cdrecord works like a charm (or as much, as I
tested ;) the problem is, I can't read them after that staying in
FreeBSD.
