Also a problem in 2.6.14. I am not using udev or devfs but have explicitely created /dev nodes (old fashioned way and far far too many entries, but ... always worked before). Newer kernels boot with many undefines. They seem to correspond to stuff in the sound core modules. Do I now need to explicitely load these or soundcore.ko on boot up (i.e. placing them in /etc/modules--somewhere along the line, snd_seq_midi had to be placed there!). Anybody doing this? (Guess it wouldn't hurt to try it.)
