I'll give it another shot then, disabling the kudzu-probing (using an Emagic
2|6 USB audio interface on the audio box, so no fancy probing necessary)...
Has anyone successfully compiled a recent 2.5 kernel using gcc 3.2-7 (Redhat
8)? I read some warnings about broken kernel optimizations with gcc 3.x -
but that might have been resolved long time ago? I will start digging into
this and see what works, audiowise.

everything from scratch?
first of all, you should refer to Documentation/Changes in the kernel
source tree and make sure all your userspace tools are up to date (the
most critical being the modutils).
then you could look at the .config file for the redhat kernel and mimick
the configuration for 2.5 (where applicable). expect some things to
break, though. i usually only do it to the point where the system works
for me and ignore any further boot-time error messages from init scripts
that miss some modules etc.
disabling hardware scanning seems to help a lot - when i tried the new
kernel on my powerbook running yellowdog, i had to disable kudzu (the
hardware scanning tool).

hello everyone!
if you are thinking about testing the new 2.6-pre kernels (which would
be helpful to shake out problems with typical audio-workloads that might
not get tested by others), here are two links worth a read (found on
lwn.net):
* the 2.5 "what to expect" document by dave jones:
http://lwn.net/Articles/39901/
* the wonderful world of linux 2.6 by joe pranevich
http://www.kniggit.net/wwol26.html
best,
jörn
