After months trying many things and after posting in arch forum[1] I am here asking if anyone could help me.Everytime I try to reboot or shutdown my computer, after turning everything off, my system hangs and display one of these messages below. a) cgroup : option or name mismatch, new: 0x0"", old: 0x4 "systemd" shutdown[1]: Failed to finalize file systems, ignoring b) A stop job is running for Daemon for power management (20s/1min 30s)I use Gnome 3, when I've changed to my DE to KDE the reboot options worked sometimes, but most of the times it didn't. After it stop working at all I've come back to Gnome, since I can't reboot my system no matter what I do. OBS: I know the cgroup message is just a warning to most of people, but for me it freezes my system and I can only turn the power off and on in order to reboot my computer, I really want some help of how can I at least search for the possible things that is causing this problem.Sorry for long e-mail.
