I have the same issue with one of my CD drive.

I have 2 DVD drives:

/dev/sr0:ASUS    DVD-E616A
/dev/sr1:SONY    DVD RW DRU-810A

This problem happens with the ASUS drive when I want to eject a mounted
CD/DVD

Another problem is the SONY: sometimes it is impossible to open/eject
this drive. But the problem described here (eject then immediately
reload does not happens.


When I use these drives, I get this warning in the logwatch report:

- --------------------- Kernel Begin ------------------------


 WARNING:  Kernel Errors Present
    ata1.00: failed to IDENTIFY (I/O error, err_mask=0x40) ...:  1 Time(s)
    ata1.01: failed to IDENTIFY (I/O error, err_mask=0x4) ...:  3 Time(s)

 ---------------------- Kernel End -------------------------


When I cannot open/eject the SONY drive, there are messages in
/var/log/messages:

Then nothing...: the drive is completely ignored whatever are my
attempts to open it, I have to reboot.
