Ok, just making sure it's indeed hal that triggers this, because quite odd..
The floppy ticking problem also goes away when your restart hal like that ?

We'll see if that matters.. Hopefully not. Could you run the attached test
program, it poll you cdroms for media status just like hal does.
The way to use it is to turn off hal, and run it with your cdrom device names
as arguments. For example ./test /dev/hdc /dev/hdd
