Bug Description

Sometimes when leaving the computer unattended, the screen turns off and the computer seems frozen. CPU seems to be working at full speed. Swithing to virtual terminals is not possible, and other actions seem not to be working (like using multi-media keys to play music). However, alt+Sysrq does work and it is able to successfully re-boot the machine.

It also happens sometimes just by closing the lid.
