But...but...that's what the eject button is for.  Seriously, the Linux
kernel does not understand "eject"?

I tried again with a working disc and saw this from "mount":
/dev/sr0 on /media/LXFDVD169 type iso9660
(ro,nosuid,nodev,uid=1000,gid=1000,iocharset=utf8,mode=0400,dmode=0500,uhelper=udisks)

I then did an eject from within "Dolphin" and did not see as "VF: busy
inodes" message.

I then inserted a failing disc (LXF 170) and there was nothing from
mount or dmesg.

The behaviour with a failing disc is also different.  With a working
disc the access light comes on, goes out, comes on again and the disc
spins to full-speed for a second or two and I'm good.  With a failing
one I see the access light it goes out and then nothing.  It stops.

I would understand some kind of disc read failure or some message
getting written to the logs; but there's nothing.

Apart from trying a Live USB, I'm tempted to see if I can temporarily
swap the DVD drives in the PCs to see if the problem follows one drive.
