Burning audio CD in DAO mode with UDMA causes hang-up

Hi,

burning an audio CD with

# cdrecord [-dummy] dev=/dev/hdg -audio -pad 1.wav [2.wav]

does crash the computer in certain situations (no real code!). To
(de-)activate DMA I use hdparm -d1 /dev/hdg or hdparm -d0 /dev/hdg. To
change between UMDA2 and MDMA2 I use hdparm -Xudma2 /dev/hdg or hdparm
-iXmdma2 /dev/hdg. I tried burning 1 or 2 .WAV files:

- If DMA is off, everything works

- If DMA is on _and_ MDMA2 is set, everything works

- If DMA is on and UDMA2 is set, the command does only work with _one_
WAV file, not more.

"Not working" means causing hang-up after some time.

/var/log/messages:

I know that this worked before (SUSE 10.0, now 10.1). Burning data CDs
in SAO/DAO works. What's happening here, I though those bloody problems
with UDMA and burning audio CDs completely vanished?!!!!? I-am-so-sick
of that kind of problems, now that it finally worked for some
years/SUSEs.

I have to add that it is /dev/hdg because it's connected to the
secondary master channel of my Promise Ultra 100 TX2 IDE controller.
But as I said: It (finally) worked, till now :-( I found some hints on
the linux.kernel mailing-list that starting with kernel 2.6.15 (now 16)
some problems re-appeared concerning IDE. I tested it with both
pdc202xx_old and pdc202xx_new.

Greetings,

René
