About the sem_wait bug many reported it's a problem related about having OpenCL/OpenGL linked with nvidia too; i'm quite confident with Debian and i removed all dependencies with OpenCL/OpenGL nvidia card on my system yet the problem still present, i guess it's something more but i can't find if it's debian or AMD related.
