Hi!
For new test results see the end of this mail.

Mandrake Control Center recognices the card as follows (partly in

Hersteller: Fortemedia, Inc
Bus: PCI
Bus: 1319:801:1319:1319
Standort auf den Bus: 0:b:0
Beschreibung: Xwave QS3000A [FM801]
Modul: snd-fm801
Medienklasse: MULTIMEDIA_AUDIO

this information came frome harddrake which uses libldetect (which is
also used by lspcidrake).

bus is vendor_id:card_id:subvendor_id:subcard_id
bus position (Standort auf den Bus) is pci_bus:pci_device:pci_function
Beschreibung is of course description of the device and Hersteller is
vendor
module is of course kernel module

the driver association is made by libldetect from
/usr/share/ldetect-lst/pcitable :

tv@vador ~ $ fgrep fm801 /usr/share/ldetect-lst/pcitable
0x1319 0x0801 "snd-fm801" "Fortemedia, Inc|Xwave QS3000A [FM801]"
0x1319 0x1000 "snd-fm801" "Fortemedia, Inc|FM801 PCI Audio"

I had no alsa installed while running hardware detection.

alsa drivers're included in mandrake kernel

No, sorry. I recompiled the kernel with sound but without alsa because I wanted to use an alsa version newer than rc2 to check if the problem was solved already. I already installed rc6 and a newer cvs version on another mdk9.0 system without problems. I should have done recompiling/installing the kernel and newer alsa version correctly.

you can check this also via lspci command.

lspcidrake -v will give him the module too

I already attached my lspci -v outputs in two previous mails, but to be sure they get to where they should ...

00:0b.0 Multimedia audio controller: Fortemedia, Inc Xwave QS3000A
[FM801] (rev a0)
Subsystem: Fortemedia, Inc: Unknown device 1319
Flags: bus master, medium devsel, latency 40, IRQ 10
I/O ports at ec00 [size=128]
Capabilities: [dc] Power Management version 1

00:0b.1 Input device controller: Fortemedia, Inc Xwave QS3000A [FM801]
(rev a0)
Subsystem: Fortemedia, Inc: Unknown device 1319
Flags: bus master, medium devsel, latency 40, IRQ 11
Capabilities: [dc] Power Management version 1

in the output of lspci in your last mail, the i/o ports and irq are
missing. please check again?

in order to have the full information, i would like Friedrich to send
us the following information (what i call the classic bug sound
tester) :

"lspcidrake -v | fgrep AUDIO" will tell you which driver your card use
by default

"grep snd-slot /etc/modules.conf" will tell you what driver it
currently uses

I threw out all entries regarding soundcards from modules.conf. modprobing the snd-fm801 module is enough to cause the problems.

"/sbin/lsmod" will enable you to check if its module (driver) is
loaded or not

no sound module is loaded (because nothing there in modules.conf) up to the point where I do a 'modprobe snd-fm801'. As soon as I do, the following modules are added:

snd-fm801 9772 0 (unused)
snd-pcm 71328 0 [snd-fm801]
snd-mpu401-uart 3840 0 [snd-fm801]
snd-rawmidi 15424 0 [snd-mpu401-uart]
snd-opl3-lib 7652 0 [snd-fm801]
snd-timer 12908 0 [snd-pcm snd-opl3-lib]
snd-hwdep 5152 0 [snd-opl3-lib]
snd-ac97-codec 31620 0 [snd-fm801]
snd 36076 0 [snd-fm801 snd-pcm snd-mpu401-uart snd-rawmidi snd-opl3-lib snd-timer snd-hwdep snd-ac97-codec]
soundcore 4068 0 [snd]

"/sbin/chkconfig --list sound" and "/sbin/chkconfig --list alsa" will
tell you if sound and alsa services're configured to be run on
initlevel 3

"aumix -q" will tell you if the sound volume is muted or not

no mixer problems

"/sbin/fuser -v /dev/dsp" will tell which program uses the sound card.

none. I've deactivated artsd and have no other sound daemon installed. The only programs that produce sound are controlled by me. (But now I know that even hitting backspace once in Konsole causes a beep that locks the system. Not really! The END of the beep does! see below)

this will tell us at which stage the problem happen

OK. I've done new tries. Now I know that modprobing snd-fm801 causes the following to be written in /var/log/messages:
Dec 13 11:53:24 localhost kernel: ALSA ../alsa-kernel/pci/fm801.c:922:
unable to grab region 0x0-0x7f

If I do not produce any sound output, the system does not lock up as I've written before (I must have caused an error beep in a KDE terminal. I've tried this: Causing a beep locks the system immediately). Sorry for the misleading information. My fault.
After another reboot (always interesting if the filesystem was damaged ;-) ), I modprobed snd-fm801 and used aplay to play a wav file. It does without problems. But at the same time the playback stops, the system locks up.
So, in summary, the critical moment is stopping playback on the fm801. I think, I've read the same problem description somewhere before. What could I try next?
Thanks for all your help so far!
