I'm using RedHat 6.1 and upgraded the kernel to 2.4.26 from 2.2.12. After upgrading, whenever I shutdown the computer, I get the following kernel messages:

Saving mixer settings modprobe: modprobe: Can't locate module sound-slot-0
modprobe: modprobe: Can't locate sound-service-0-0
aumix: error opening mixer
Unmounting file systems: OK
No automatic removal: Please use unmount/proc
INIT: no more processes left in this runlevel.

After this message the computer hang up.
Please help.
