Since cdrom is modular the sysctl setting is not always effective, even if shipped. It is not applied in early userspace in the initramfs, either. To be able to disable autoclose reliably adding the SLE patch to the master is the only way. On the other hand the observed behavior is due to some broken application polling the drive. Linux has an interface for polling optical drives without triggering the autoclose: opening the drive with O_NONBLOCK. -- You are receiving this mail because: You are on the CC list for the bug.
