When I do something (whatever) that results in a shut down, restart or sleep (for example usual shut down or restart, closing the lid, etc.), fedora 18 (x86_64 , GNOME desktop) comes up with an error (below). Can you help me with this?
Not all file systems unmounted, 1 left cannot finalize remaining file systems and devices, giving up
Should I unmount added devices (other drives) manually before shutdown?
I tried, as user:IBr suggested, to reboot from tty and it worked. So the problem occurs only in GNOME.
