Hello.
short:
[2.6.18] ATI IXP - Unknown symbol -> no sound
longer:
I have an ATI IXP sound card, and since kernel 2.6.17, sometimes I have no sound
when I boot.
The card dosn't appear in /proc/asound/cards
The relevant log part are given below
What is weird is that the modules are loaded, and that it doesn't happen
everytime.
I have a P4 with hyperthreading enabled (I don't know if it plays a part).
The thing is that before 2.6.17, I never had problems
If you need any information or anything, feel free to ask.

Sounds like your ALSA modules were built against a different kernel.

Hi.
Thanks for your reply, but it can't be this, because I build my own kernel.
I tried with vanilla kernel, and Debian's one, but I'm still experiencing these
problems. What's weird is that this doesn't happen everytime, maye one out of
5, or something, and I never had these kind of problems with <= 2.6.15
Well, I could just not use modules, but I'd like to know what's going wrong, and
if it's a kernel bug, have it spotted and hopefully fixed.
cheers
