Comment 49 for bug 656279

I definitively understand the problem.
on i5 cpu systems as mine, if you disable logic cpu all will work fine.

I done:
echo 0 > /sys/devices/system/cpu/cpu1/online
echo 0 > /sys/devices/system/cpu/cpu3/online

and when I wake up my system all works fine and smooth (flash full screen
videos too)
