on my original problem with alsa module cs46xx freezing during a suspend, I noticed that cs46xx survives hibernation (initiated with the Thinkpad utility tpctl --H). Quite strange then that suspending (using either 'apm -s' or 'tpctl --Z' freezes alsa.
Any ideas how to approach this problem?
Thank you.
best regards,
Jan
P.S. Also I upgraded to the latest Thinkpad BIOS version - which didn't help.

Hi,
when I suspend on my
Thinkpad A22p (Crystal cs4614/22/24 sound chip)
running a fresh
(and seperate) alsa 0.9.6 installation,
the alsa module cs46xx seems to freeze (i.e. various sound players can open the sound device either natively or as oss emulation but not start playing anything).
After reloading snd-cs46xx.o by
rmmod snd-cs46xx; usleep 500; modprobe snd-cs46xx; sleep 1; alsactl restore
the sound system can be made functional again. (sometimes a second attempt or setting the volume manually is necessary though). Unloading the module before suspending and modprobing the module after resume doesn't help but gives the following message in /var/log/messages:
kernel: ALSA ../../alsa-kernel/pci/cs46xx/dsp_spos.c:1840: dsp_spos: SPIOWriteTask not responding
(Hence work arounds a la apmd will not be really reliable)
Also sometimes when reloading the module I get:
insmod: insmod: a module named snd-cs46xx already exists
This is quite a nuissance to me. Suspend actually worked well with alsa ov the v0.5 series but with kernel 2.4.20 I understand that I can not downgrade (got many compilations errors).
If you look at my configuration details below, can you recognize any errors on my side? If not, how could this be fixed? Even though I am not a kernel programmer, I could help in running test code with debugging settings on my machine.
Any help/hints would be greatly appreciated.
regards,
Jan
BTW: I do always have to run depmod -a to activate changes in /etc/modules.conf, correct?
P.S. I have CC:'ed you, Chris Gianniotis, in case you're still interested in my modules.conf - or maybe you even have the same problem on your A22p.
P.P.S. Putting the machine in suspend mode was done with any of the following three methods: calling 'apm -s', pressing the suspend button, calling tpctl --Z to suspend through the BIOS. ACPI is disabled but compiled into the kernel.
=========================================== Thinkpad A22p Model: 2629-YVU the PCI Power Management (if I have it) could be on - I could check that if needed SuSE v8.2 (custom, SuSE derived) Kernel 2.4.20 compiled with both APM and ACPI but ACPI is disabled by kernel option acpi=off, suspend/hibernation work only with apm devfs is off - strange SuSE default (seperate) Alsa packages v0.9.6
