Sticky button, I don't think so, I must have used that CD drive twice, only to run FreeBSD installation CD. Faulty hardware? Possibly, it happens on both machines with tha mother board and never on others. > Otherwise, you'ld have to send a specific command to the device to make > it open up -- something that would be pretty unlikely to happen > randomly.

Perhaps hald/dbus -- not that there's > any reason to run those on a dedicated DB server? I am not running any of these, as far as I know, it could be an SCSI bus reset? But then it is hardware and back to the above explanation. Thanks anyway. Olivier
