You should also be able to solve this problem by looking in
/etc/sysconfig/suspend, which will still allow you to "run" the
services, but avoid the lockups.

It loads up the relevant modules (either OSS or ALSA), and
saves/restores your mixer settings.

You should be able to see the description of the service in the Mandrake
Control Center->System->Services by clicking on the "info" button. If
you think the description isn't good enough, you can file a bug at
