--- Comment #42 from Jose P. lbdkmjdf@sharklasers.com --- I'm using kernel 3.13-rc0 from: http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-next/2013-11-14-trusty/ 3.12.0-996-generic #201311140516 and this is still happening... I guess I'll have to go back to fglrx. I wished I could help devs, but this is driving me crazy. Not being able to resume from suspend is why I wanted to test the open-source driver in the first place...
