Description of problem:
We are trying to setup Oracle over RHAS2.1 on an IBM xSeries x342 and we got 
errors while reading from IDE cdrom.
We can see this kind of errors:
Oct 30 19:48:56 elena kernel: Curious - OSB4 thinks the DMA is still running.
Oct 30 19:48:56 elena kernel: OSB4 wait exit.
Oct 30 19:48:56 elena kernel: hda: cdrom_decode_status: status=0x51 { 
DriveReady SeekComplete Error }
Oct 30 19:48:56 elena kernel: hda: cdrom_decode_status: error=0x34

We have already tried to boot with ide=nodma and hdparm -d 0 /dev/hda but the 
problem still appears (not so often, 1 out of 5 times instead of 1 out of 2, 
but still there).

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.mout Oracle CD2 
2.Try to copy (cp) cd contents from CD to sda.
3. Some time in the middle of that cp process system nearly hangs and shows 
error messages like stated above.

Actual Results:  system nearly hangs, this means you can switch between 
consoles but you can't umount CD or kill the cp process...

Expected Results:  succesful copy, no system hang.

Additional info:

We have already updated to kernel 2.4.9.e8.smp
Same behaviour occurs with other CDs (not only Oracle one)
Server comes with Serverworks HE-SL chipset with OSB4 for IDE.
