Hm, maybe you are right with your kernel presumption. It is quite possible.
Perhaps it is a bug in kded's media manager.
I did some more tests and found out that hal is not the absolute reason for
this problem.
After stopping kded's media manager and hald, restarting hald
with "hald --daemon=no --verbose=yes" i got the messages:
