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? -- Hasso Tepper
