Description

Hi,

I switched to current (7 Jan) from preview to try the new dri. Now
when I try to watch a DVD video (or read it in any way) the process reading
the DVD locks and I get errors like this in the log:

---------------
Jan 10 20:17:50 df1 kernel: ata0: FAILURE - non aligned DMA transfer
attempted Jan 10 20:17:50 df1 kernel: acd0: setting up DMA failed
---------------

Possibly related - atacontrol doesn't seem to work

atacontrol list - just hangs

atacontrol mode 0 - gives

atacontrol: ioctl(ATAGMODE): Inappropriate ioctl for device

I was about to add that burning and mounting data discs works fine
when I noticed that these use /dev/cd0 not /dev/acd0, which led me to
discover that watching DVDs from /dev/cd0 works fine.
I am using nata, which has worked fine before now.
Hardware is an ASUS A8V motherboard - DVD drives are both LiteOn
(LH-20A1P and SOHD-167T) UDMA33. The SATA hard disc works fine.
