kernel oops on snd-powermac
hello list !
I just installed debian sid on the powerbook G4 12" I bought two weeks ago.
Sound was working quite fine with Linux version 2.6.15-1-powerpc (Debian
2.6.15-8) (waldi@debian.org) Mon Mar 6 12:39:17 CET 2006.
Now that I updated to Linux version 2.6.16-1-powerpc (Debian 2.6.16-9)
(waldi@debian.org) Thu Apr 20 17:23:17 CEST 2006, I get a kernel oops
whenever snd-powermac is loaded (attached is a pure dmesg extract ).
Of course I don't get sound after that.
Anyone experiencing trouble with this kernel version ?
