I have also this problem on almost all my machines .. the only solution
I found is to disable DMA (atapi_dma), but then performances are very
poor ..
If you find a solution please let us know :)

Hello,
I'v been having problems getting this DVD drive working at all, I'm
running on 6.3 p1..
On boot it is detected as:
acd0: DMA limited to UDMA33, controller found non-ATA66 cable
acd0: DVDR ATAPI DVD A DH20A4P/9P57 at ata0-master UDMA33
Which is the first sign of trouble, it is connected by an ATA66
capable cable and I'v tried swapping over the cable to rule out a
faulty cable and the message is the same.
It is connected to:
atapci0: Intel ICH6 UDMA100 controller port
0x1f0-0x1f7,0x3f6,0x170-0x177,0x376,0xffa0-0xffaf irq 16 at device
31.1 on pci0
ata0: ATA channel 0 on atapci0
ata1: ATA channel 1 on atapci0
When trying to use burncd on it, the drives light flashes for a while
then after a delay I get:
acd0: FAILURE - READ_TRACK_INFO ILLEGAL REQUEST asc=0x24 ascq=0x00
On the console and any further attempt to use the drive results in
that message being repeated without any delay, also trying to use the
atapiscsi device results in a similar message:
acd0: FAILURE - INQUIRY ILLEGAL REQUEST asc=0x24 ascq=0x00
Any thoughts on what problem here is? It seems that the controller
isn't working properly with it?
Cheers,
J.
