Comment 12 for bug 1577120

Same issue here (KDE Neon 5.10, based on Ubuntu 16.04; last dist-upgrade today). When I'm trying to shutdown and press ESC on the Splashscreen I see the message "A stop job is running for <mountname>" with a timeout. When the timeout is reached, it is prolonged (at first ist was 1 minute 41, then 3 minutes 11, then 4 minutes 41, ...) but nothing more happens.

This occurs when mounting at startup via fstab and also when commenting out fstab entries for startup and doing manual "mount -a" after startup.

Sadly, Workaround from Post#4 didn't work for me.
