By the way... i used the alsa-headers-9999 from Oct 29 21:28
Damned...I'v forgotten some additional infos: This error happens with 2.6.27-r1 as also with 2.6.25-r7
Is this a regression, or does alsa 1.0.17 oops as well? Also, please show your sound card model in case this is model-specific (output of lspci will show it)

I'm currently switched over to the kernel internal drivers on 2.6.27-r1, an they are working well. I'll try out tomorrow what happens if I use alsa-driver-1.0.17

@beandog: What is the support policy for media-sound/alsa-driver these days? Could be useful if you described it in <metadata.xml>.
Same problem here. Seems to be a known regression that has already been fixed: http://www.mail-archive.com/alsa-user%40lists.sourceforge.net/msg23608.html
Also, alsa drivers 1.0.18 were released on October 29. From the changelog 1.0.18rc3 -> 1.0.18: "ALSA: hda: fix oopses in snd-hda-intel after digital slave support additions" as the oops was within snd_ctl_make_virtual_master, I guess that this is the problem we are talking about.
