[Bug 1511019] [NEW] Ubuntu 15.10 freezes occasionally

 

Public bug reported:

Lenovo G50-30 WIly 15.10 freezes! 
More often when I use touchpad, less with a mouse. Always freezes when streaming a video from youtube in the browser or Totem player. Keyboard is inactive after the freeze so nothing helps only reboot. Also happened in 15.04. 

After several reboots like that it's impossible to switch off the laptop
from OS interface - it hangs on and on and I finally have to press
switch-off button.
