As has been said, Mandrake 8.1 uses devsf...which seems pretty flakey to
me at this point. On my system I just turned it off, and all of the
device issues I was having, including the one you describe, magically

To turn it off, edit lilo.conf for your main boot entry. Add
"devsf=nomount quiet". Here's the first entry from mine:

        append=" hdd=ide-scsi devfs=nomount quiet mem=512M"

Reboot, and that's it. To renable it, just change "nomount" to "mount.
