You mean RH 8 right? Cause if your using RH 9 then you didn't get it from
redhat :) hehe
Anyways, I've been having the same problem. I can't get UDMA or DMA to work on my
DVD-ROM with RH 8. It works fine with all the 7.x releases. I haven't figured out
yet what is wrong but it's really anonying because I can't play DVDs in redhat 8
when I could in redhat 7.3
Anyone have any ideas?
Thanks,

with similiar message log and hdparm results. I will focus on the workstation right
now but getting DMA working on the laptop would be nice too. I actually boot and
run from 3 SCSI drives, and have the two IDE drives (CD and DVD) on the same 1st
IDE channel.

message log "seems" to indicate UDMA support and hda and hdb using DMA, but as can
be seen by the hdparm output they are not and wont accept dparm -d1 /dev/hda. I
have also tried butting with ide1=dma and ide2-dma as kernel parameters, but still
no cigar (or smooth DVD playback).
