I had the same thing recently, IIRC it was a kernel version bump that
disabled several kernel configs including BLK_DEV_(your chipset_here)
after rebuilding I was again able to enable DMA

Greetings all,
I'm running debian unstable on 2.4.18 kernel and have to cd drives, one
is a cd writer and the other is a dvd player. A while ago I was getting
jumpy DVD playback but found (via a website) that 'hdparm -d1 /dev/dvd'
solved it wonderfully.
However, a while ago I needed to burn some CDs so I found a walkthrough
that had me adding a SCSI module (I believe) and now when I try to run
the above command I get amancha:/home/slosh# hdparm -d1 /dev/dvd
/dev/dvd:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Invalid argument
and needless to say the DVD playback is jumpy again. What do I need to
do?
