No one can reproduce it./ Not quite true. This bug was current till today in Mandrake's kernel, but with 2.6.11-5mdk they managed to get rid of it. The problem is not with loading the driver but when alsactl tries to store/restore mixer settings. I have tried again with 2.6.12-rc1-mm1 and it is still there (for example the Gnome won't start due to this).
