and tried to suspend-to-ram without quirks (only via pm-suspend from VT1 - no X
yet) and it worked,resume also worked - so no hardlock or crash in that process
[yet]

but after resume, starting up X (lightdm) and logging into Xfce 

the composited desktop was very very slow again (I tested "inverted colors"
effect and tab-switching between apps which worked)

output of dmesg also was displayed

switched from compiz(fusion) to xfwm4 - moving the gnome-terminal window via
pressed left mouse-button & mouse was laggy and with delay / trail

output of dmesg still was displayed without crash or hardlock

switched back to compiz-fusion (switching is done via fusion-icon)


now I wanted to post some preliminary info here - so fired up firefox and
screen went black

--> totally black, after several seconds and magic sysrq key + r & switching to
VT things got displayed again



dmesg from after resume:
