I can verify the same observations on my HD 7850 (PITCAIRN 0x1002:0x6819
0x1787:0x2320) card.  I use Linux stable kernels with Radeon DRM (and core DRM)
cherry-picked in from drm-next and drm-fixes.  With my last local update --
from
kernel 4.0.4 + DRM 4.1 cherry-picks, to 4.0.6 + DRM 4.1 + DRM 4.2 -- running
'alien-arena' as a test program causes the DE (also Xfce, as is the case with
hadack) to stop responding once I exit the game; also, the DE itself seems to
trigger the bug after a while, or when resuming from suspend.

I tried the patch mentioned in comment 2 ("drm/radeon: fix adding all VAs to
the freed list on remove v2"), but the symptoms described above continued.

Reverting 161ab658, and not applying the "fix ... VAs ... v2" patch, gives me a
working kernel.  (And one I am very happy with!  My current combination of LLVM
3.7, Mesa, libdrm, xf86-video-ati, and xorg-server is the fastest, most
responsive system I've ever had with open source drivers.)
