To clarify the state of the bug ...

The issue with SATA CD/DVD devices causing interrupt storms etc are solved 
in both master and 2.0 branch. There are still issue with recording 
though:

acd0: FAILURE - READ_BUFFER ILLEGAL REQUEST asc=0x24 ascq=0x00
acd0: FAILURE - READ_BUFFER ILLEGAL 
ata4: FAILURE - non aligned DMA transfer 
acd0: setting up DMA failed

I think that it's not specific to SATA CD/DVD writers though. And I 
thought Matt already fixed the issues with non aligned DMA transfers? Or 
was it in different path?

I don't have time and knowledge to work on this, but I think that it's 
showstopper for 2.2. Any takers?
