Hello,

I tested many hours before I sent you this eMail. I never
sent Bug-Reports, so please be friendly if I did something
wrong :-)

I used the formular to produce a bug-report:

1.) See subject
2.) I have trouble using DMA mode with my Siemens Fujitsu
harddisk on a NMC 6vcx Motherboard. I compiled the kernel
with DMA support, multi mode VIA chipset support and booting
DMA by default when available.

I used the command "updatedb" and "find" and "bonnie" to have much
read access. No problem occurs.

I used xmms to convert mp3-files into wav. There I get many
errors of the following:

hda: dma_intr status=0x51 {DriveReadySeekComplete Error}
hda: dma_intr  error=0x84 {DriveStatusError BadCRC}

I do not want to run the harddisk in PIO mode. I used hdparm
to change some settings (infos from SuSE Support database)

hdparm -d 1 -c 0 -X66 /dev/hda (also without -X66)
and
hdparm -d 1 -c 1 -X66 /dev/hda (also without -X66)
at least
hdparm -d 0 /dev/hda

Nothing changed. (only performance maybe)

3.) Keywords: (U)DMA
4.) Linux version 2.4.0-test11 (root@informatik) (gcc
version 2.95.2 19991024 (release)) #15 Wed Nov 22 18:40:38
CET 2000
5.) No Oops Output available
6.) Xmms is able to produce the error by using the
diskwriter modul

I hope that is all you need on information. The problem does
not occur with Kernel 2.2.16 (SuSE-patch)

Please let me know, if that is/was a bug. If I did something
wrong with configuration, I was thankful for helping me
fixing the problem.
