Could you attach (don't paste) the full kernel message? The important part is missing in the above. Created attachment 69662 [details]
full kernel log since starting skype
Ok, now the full messages are attached starting with opening skype.
Thanks. How often does this occur? At each time, or at random? Also could you apply the debug patch below and see what are printed? Created attachment 69762 [details]
debug patch
Nearly every time, At least with kernel version 3 it happened every time I tested it. Before there where times where no problem occurred at all. For the patch I will have to see how to apply it to the archlinux kernel. Will probably take some time. Hm, so it's a kernel regression at some time? Anyway, try the patch below, too. If the bug is because of a race, it might be fixed by this. Created attachment 69812 [details]
test fix patch
Against which kernel version is the first patch? It doesn't apply to 3.0.3 And for both patches: is it ok to exchange the snd_hda_intel module or do I have to change more for testing it? During the last few days I have tried to reproduce the problem with the 3.2.6 kernel and I cannot get it again. Seems this has gone completely. No more problems with a recent kernel. |
