If I've disassembled this correctly, the crash happens in the first call to snd_hda_add_nid() because nids is NULL.
Please do the following: - load snd-hda-intel with probe_only=1 option - run alsa-info.sh (with --no-upload option), then attach the content.
Hello, I'm a newbe and can not understand what I should do. Please give me exact information what should I do on console or kernel-option. I can't find 'alsa-info.sh'. with regards Ch.

The script is found in http://www.alsa-project.org/alsa-info.sh The detailed information about HD-audio driver is found in Documentation/sound/alsa/HD-Audio.txt. In this case, add probe_only=1 option to snd-hda-intel module, typically somewhere in /etc/modprobe.d/* file. This will skip parsing the codec content, thus we can get the register access without Oops. Note that the option for snd-hda-intel is different from the option for snd. Some distros have modprobe configs like options snd slots=xxx ... This line isn't for snd-hda-intel. The options for snd-hda-intel is like options snd-hda-intel ....
Hello, I have now in the /etc/modprobe.d/sound.conf following content: options snd-hda-intel model=lenovo-nb0763 options snd-hda-intel probe_only=1 The output from alsa-info.sh you can find here http://www.alsa-project.org/db/?f=3eb2b7a6370bc4028ab19ca81d5d7e7d4c331c42 I hope, you can find out the kernel bug now. with regards ch.

(In reply to comment #9) > Hello, > I have no experience and have no idea what should I do now with that. > Please give me more information how can I do this patch. The easiest way is to contact with the distributor and ask them for providing a test kernel with the given patch. Of course, you can build the kernel by yourself if you'd like.
Hello Takashi Iwai, your patch is integrated in kernel 2.6.34-0.slh.9-sidux-686 and works fine on my machine. Thanks to you. with regards Ch.
