Any help in finding bugs (audio or otherwise) in udev is greatly
appreciated. Usually they are easy to fix once we have a report, the
problem is finding people who can report and reproduce them.

I had a look at the udev in fedora (rawhide) and it should be almost
identical to what we have in testing. It would be useful to know
exactly what versions you are using (the newer the better) on both
Arch and Fedora of both udev and the kernel, as well as more details
about your problems:
Do you have missing devices? Are there any differences between the
loaded modules in a working and a broken system? Can you find any udev
or module related bugs in your logs or dmesg? A useful exercise is to
do "modprobe -rv <relevant module> && modprobe -v <relevant module>"
and look on the console as well as dmes.

If you have a pinned down a bit what the problem is, then open a FS,
if you are still lost feel free to ping me in #archlinux (I'm
tomegun).

Cheers,

Tom
