I'm sorry to say that, Yes.
I finially compiled a fresh 2.6.13-rc4-git1 kernel with ck-patch and
Gregh-kh patches.
With this kernel non of the problems I had with mm-kernel are present.
Here is everthing just perfect..now
I attached a dmesg output for review :-)
The Oops on probing snd-hda-intel gone. It works now ... Mozart rocks :-)
I look at the CVS tree of Alsa later.
I finialy converted my reiser4 root to reiser 3.6.
Where I can get acpidumb or what it is called?
