I use nVidia GeForce 8200 and when booting I get some errors regarding Nouveau driver.

PS: I can't use nVidia blob driver because I've given up on solving nasty error which made my PC crash after some time in Gnome Shell just showing fragments all over my monitor.

OK, seems that those errors do affect something after all.
After I suspend and resume (doesn't matter if with systemd or pm-utils) the PC will freeze when I fullscreen video in smplayer. In that situation I still can switch to other TTY and kill smplayer from there, but it is annoying.
I get no errors about the freeze in either Xorg.0.log, nor journalctl.
The freeze isn't happening with freshly booted PC (not suspended).
So I'm guessing that those errors mentioned in the previous post are some bad memory links which are ignored by those suspend scripts.
