Description Thorsten Hirsch 2016-07-03 21:38:08 UTC 
My OpenGL game freezes and I see the following errors in dmesg as soon as the video sequences have finished and the game should start:

The game is Alien Isolation (steam version).
GPU: AMD Radeon RX 480
OS: ArchLinux
Kernel: 4.7.0-rc2-g0812a94 (polaris-test branch of linux-git repo from freedesktop.org with latest firmware)
mesa/libdrm/llvm/xf86-video-amdgpu are all built from git
Comment 1 Michel Dänzer 2016-07-04 01:53:39 UTC 
Could be bug 96731.
Comment 2 Nicolai Hähnle 2016-07-04 15:42:35 UTC 
Yes, the symptoms were the same. Please try the patch there: http://reviews.llvm.org/D21975
Comment 3 Thorsten Hirsch 2016-07-04 21:44:31 UTC 
Yes, the patch works. Alien Isolation now runs flawless with amdgpu driver (w/o amdgpu-pro).
