This problem has been bugging me for a long time - excessive CPU usage with gvfs-gdu-volume, udisks-daemon and dbus-daemon

I have had this problem on Lucid and Karmic - fresh installs.

Looks like it is down to my Optiarc ad-7640S DVD drive.

This command "fixes" the problem for me too:

sudo hal-disable-polling --device /dev/sr0

Works for me too.
