FYI I see a similar GPU stalls/display blanks with an upgrade from 10.1.4 -> 10.2.1. I am on Verde with VERDE_mc2.bin.
I started bisecting, but it takes me about a day to judge good vs bad, and as I have around 1000 commits in front of me, this will take about 10 days.
I am also on Arch. xorg-server=1.15.1, xf86-video-ati=7.3.0. linux=3.15.2.
Kernel 3.15 is indeed unstable on Cape Verde. We know where the problem is. If kernel 3.14 doesn't hang the GPU for you, it's the same problem.
