    Thanks for the link.

    It cannot be hal in my case as I've disabled polling by hal for both
    drives using the 'hal-disable-polling' command.

    The bug report also mentions udev, but I'm not sure if that's it either
    as the bit in the report is about sr* devices, which is SCSI/SATA and
    the patch linked there is in Debian's udev.
    The udev changelog for Debian has:
    udev (0.125-4) unstable; urgency=medium
    * 60-persistent-storage.rules: do not run vol_id on media tray open
    events or the kernel will close the tray again.

    Hmm, in Debian unstable /etc/udev/rules.d/60-persistent-storage.rules
    also has:
    # skip removable ide devices, because open(2) on them causes an events loop
    KERNEL=="hd*[!0-9]", ATTR{removable}=="1", DRIVERS=="ide-cs|ide-floppy", \

    I wonder if we've got a simple case of a typo here: ide-cs instead of
    ide-cd? However, there is such a thing as an ide-cs driver (legacy driver
    for PCMCIA IDE/ATA disk cards).
    But it does seem logical that rule should also cover IDE CDs...
