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.
Can you get the monitors working again by plugging their power cable out and back in?

That doesn't work either.
