[Alsa-user] fm801 locks system

[Friedrich Ewaldt]

Hi,

because the alsa drivers shipped with Mandrake 9.0 (RPMs, version 0.9.0rc2) locked my system hard when using my fm801 soundcard, I recompiled the kernel with sound support and without alsa, compiled alsa-dirvers, -lib and utils version 0.9.0rc6 (I have the correct kernel sources of the running kernel installed) and installed them. But the problem persitst:
The system locks hard (num lock doesn't respond to keypresses, no magic sysreq. keys working...) some seconds after modprobing the snd-fm801 module. I recompiled alsa-drivers with 'debug=detect' switch and that's what I find as last messages in my /var/log/messages before the system hangs :

Dec 8 20:37:59 localhost kernel: PCI: Found IRQ 10 for device 00:0b.0
Dec 8 20:37:59 localhost kernel: PCI: Sharing IRQ 10 with 00:07.2

Dec 8 20:37:59 localhost kernel: ALSA ../alsa-kernel/pci/fm801.c:922: unable to grab region 0x0-0x7f

If this helps, here's my lspci output:

Any ideas what's the reason for my problems? Maybe it has something to do with IRQs (IRQ 10 an IRQ 11 shared with other devices)? If it is an IRQ problem, what could I do to solve it? Or - is this a known problem with FM801?

Many thanks in advance for your help!
