Subjectalsa 1.0.11, 2.6.17-rc6-mm2, kernel BUG
From
Hi all!

I have 2.6.17-rc6-mm2 running, and I wanted to try alsa drivers 1.0.11
final to get my hda-intel sound device running.

I compiled the drivers (changing system_utsname.xxx to utsname()->xxx)
and wanted to load the modules, but when I load the module snd:
BUG: unable to handle kernel paging request at virtual address 07400041
printing eip:
