This is an assumption, Udev is the subsystem that handles media eject
button events. The problem can be circumvented by commenting out the
“media eject button pressed” handling in
/lib/udev/rules.d/60-cdrom_id.rules.

  # ENV{DISK_EJECT_REQUEST}=="?*", RUN+="cdrom_id --eject-media $devnode", GOTO="cdrom_end"

(which does prove nothing). This might be a problem elsewhere,
p.e. the kernel issuing a spurious media eject button press event.
