Hi,
I am running 64 bit Arch Linux on kernel 3.15, the bug also occured with 3.14,
with Intel i5 processor and a AMD Radeon HD7770 graphics card. After a while
(randomly), both monitors go to sleep. Sometimes, they wake up after 10-20
seconds and I can continue using the computer, but more often they won't and it
requires a hard reboot. When this happens the sound continues playing. Also,
rarely the computer freezes, the monitors stay active and all I can move is my
mouse, also requiring a hard boot.
