Suspend/resume broken on Lenovo laptops (Fedora 21 beta)

Just a quick update - i got suspend/resume to once randomly work in
LXDE environment, but after that again everytime it failed.

Then I tried using "debugging" kernel on GRUB menu, and now each time
I tried suspend/resume in all environments (GNOME 3, LXDE, Cinnamon,
XFCE) it worked every time as expected.
