No entry in /etc/fstab. No other packages installt like pmount or something else.
I ran in the same error for about 6 month and could solve it, with installing libblkid from stretch.
What I try to solve it.
install anew lbblkid from stretch higher version since for 6 month
try differnet USB-Cable
control that dbus-launch thunar is in my autostart
- Try differnet DVD's
I use the DVD-Device rarely, so I don't know when the Problem came back.
In apt-history I found a Kernel-upgrade and an upgrade for eject.
I found out it is no Kernel-Problem or with systemd. Kernel from oldstable and boot with sysv-init doesn't help.
Edit2 it is not a hardware-problem. Booting Live-session works proper.
