With linux-2.6.7-gentoo-r1, I get an oops message when unloading alsa drivers. The module causing the problem seems to be snd_mpu401_uart. Reproducible: Always Steps to Reproduce: 1. /etc/init.d/alsasound stop
Created attachment 33944 [details] oops message

Hm, this looks like an upstream bug, care to file it at bugzilla.kernel.org instead of here?
