Public bug reported:

after today's upgrade to newest kernel (07/12/2014 - kernel 3.13.0-33) system 
at first bot up, but the loading screen flickered heavily, but booted to normal 
functioning login screen.
I've turned it off - and the flickering continued on turning off screen as 
well. Another try resulted in my laptop panic signal. I was able to get only to 
bios for about 10 minutes - couldn't even boot up to ubuntu live from usb.

Right now I booted to 3.13.0-32 kernel.
