Re: [alsa-devel] snd_vortex_dev_free() BUG: unable to handle kernel NULL pointer
2012/3/15, Andrew Vagin avagin@gmail.com:
Hello,
In this case I try to reload modules and get this bug. # killall pulseaudio; rmmod snd_au8830 snd_hda_intel snd_seq snd_ac97_codec ac97_bus snd_hda_codec snd_hwdep snd_mpu401_uart snd_pcm snd_rawmidi snd_seq_device snd_pcm snd_timer snd_page_alloc snd # modprobe snd_au8830

Does your hda-intel work properly?
speaker-test -c 2 -t wav -Dhw:Intel
any error message in system log before you unload the module, your output only show the error after reload ?
does "aplay -l" alway show two cards for every reboot ?
if your on-board hda-intel can only be loaded randomly, pulseaudio server may behave differently since default is on-board sound card
Sometimes my sound card hangs up (It do not produce sounds. Applications which try to play something hangs).
As your au8830 have stac9708
Did you select surround40 or stereo analog output profile ?
APLAY
**** List of PLAYBACK Hardware Devices **** card 0: au8830 [Aureal Vortex au8830], device 0: Aureal Vortex 2 ADB [au8830 adb] Subdevices: 32/32
http://git.alsa-project.org/?p=alsa-kernel.git&a=search&h=HEAD&s...
since you still have 32 playback subdevices
did you have commit fb65c2dfe60d38be6b9193d0b85e66e780cd4373
without this patch, the front and rear can be played correct once and swapped afterwards on my au8830
speaker-test -c 4 -t wav -Dsurround40:au8830
Are you sure that pulseaudio server is still running ?
if pulseaudio server crash but you still have an application using hw:au8830
it won't respwan because is_card_busy() in commit d6fb8d10819bebc1cee203de7330cceeafde9fed
udev: check busy status of alsa cards before loading alsa modules and hence initiating profile probing
Try
speaker-test -c 2 -t wav -D hw:au8830
speaker-test -c 4 -t wav -D hw:au8830
Does you enable power saving or the computer enter suspend/resume cycle ?
https://bugzilla.redhat.com/show_bug.cgi?id=789156
Sound au8830 does not work after standby mode
Can you try Taskashi 's patch and reply back to alsa-developer mailing list
The kernel doesn't panic with this patches, but a sound card doesn't work.
The origin problem is that sometimes my sound card stops to play anything. I try to reload the module to fix that, but it doesn't help. I can provide any info which you need to investigate this problem.

[PATCH - ALSA 1/2] Au88x0 - Support 4 channels playback when AC97 codecs has SDAC bit
- Check SDAC bit of AC97 codec for supporting 4 channels playback.
[PATCH - ALSA 2/2] Au88x0 - Reduce the number of playback subdevices of au8830 from 32 to 16
- The maximum number of playback streams depend on the number of sample rate conveters (16) and the number of DMA channels (32).
Applied both patches. Thanks.
Does alsa require the driver to provide private_free for ac97_bus and ac97 ?
No, and it must be irrelevant.
There is a bug report
snd_vortex_dev_free() BUG: unable to handle kernel NULL pointer
https://bugzilla.redhat.com/show_bug.cgi?id=788978
It seem that snd_ac97_bus() fail
Or something else. au88x0 is built in a strange way, sourcing all *.c files into one, so we can't see the exact point.
In anyway, the Oops isn't because the probing fails but due to concurrent accesses while removing irq, etc. Maybe a patch like below can help.
when there is more than one sound card and I need to specify index to all sound cards in order to let them loaded in the specified order especially when I have my usb webcam plugged
just specify index=0 in one sound card is not enough and some of them may failed at snd_card_create() without any error mesasge in system log
However I cannot reproduce the bug in 2.6 kernel,
Do 3.x kernel require mixer created after pcm devices ?
No.
