Problems during boot in snd_powermac with linux-image-2.6.16-rc5-powerpc
Hi
I just installed linux-image-2.6.16-rc5-powerpc. My sound does not work and
alsa complains of a missing /dev/mixer. But the most strange thing are the
following lines in syslog:

I found a thread about a similar problem under
http://lists.debian.org/debian-powerpc/2006/02/msg00350.html
but it didn't come to a conclusion.
Any hint would be welcome.
Best regards
