Version: (using Devel) Installed from: Compiled sources This is similar to #159473. I had an disc in my DVD with mp3's I listened to. I suspended the computer and resumed. Now the disc is not shown in the notifier applet, nor as mounted or umounted. It is unmounted after resume (which is probably outside of KDE's control), but at least is should show that the device and the disc exists. I have to take out and put back the disc to make it appear (or you the command line to mount it...)
Btw, if I take out and put it back, it becomes mounted automatically (this is good).
mm perhaps a problem with solid...I can't try my suspend doesn't work on my laptop...
Fixed
