acd0: FAILURE - TEST_UNIT_READY timed out

[Olivier Regnier]

Hello,

I have a Acer Aspire 3000 with cd/dvd burner "DVDR Slimtype DVDRW 
SOSW-833S VRS2" but when booting or mounting cd's, i get various 
messages that says :

acd0: FAILURE - MODE_SENSE_BIG timed out
acd0: FAILURE - MODE_SENSE_BIG timed out

or :

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

and :

acd0: WARNING - TEST_UNIT_READY taskqueue timeout - completing request directly
acd0: WARNING - TEST_UNIT_READY freeing taskqueue zombie request
acd0: WARNING - PREVENT_ALLOW taskqueue timeout - completing request directly
acd0: WARNING - PREVENT_ALLOW freeing taskqueue zombie request

I'm running on FreeBSD 6.2.

It has not been fixed since since FreeBSD 5.3.

Thank you.
