Subject:   DVD drive causes kernel blocks

In my laptop, I have a DVD drive, recognized as:

acd0: DVDR <Slimtype DVDRW SOSW-833S/VRS2> at ata1-master UDMA33

Every few minutes, the kernel reports messages like

acd0: FAILURE - PREVENT_ALLOW timed out
acd0: FAILURE - TEST_UNIT_READY timed out

and the kernel pauses at about the same time for a few seconds, causing a pause of whatever I'm doing.

Can this be resolved?
