OK, now I have enabled bfq, but ever other time it comes out of 
suspension it gets totally stuck:
I either get black screen where I only can move the mouse or the login 
screen that doesn't accept my password with no message no nothing. If I 
switch to a virtual console, as soon as I enter the username it blocks 
and I have to reset the machine.
In a sense it worked hough: it doesn't have enough time to leak memory ;-)
