After switching from CONFIG_DRM_RADEON to CONFIG_DRM_AMDGPU with kernel-4.2.3 on Kaveri-CPU, I hit that weird problem that OpenGL doesn't seem to work for non- root users with media-libs/mesa-11.0.3 and VIDEO_CARDS="amdgpu radeonsi": $ LIBGL_DEBUG="verbose" glxgears MESA-LOADER: could not create udev device for fd 4 libGL: OpenDriver: trying /usr/lib64/dri/tls/amdgpu_dri.so libGL: OpenDriver: trying /usr/lib64/dri/amdgpu_dri.so libGL: dlopen /usr/lib64/dri/amdgpu_dri.so failed (/usr/lib64/dri/amdgpu_dri.so: cannot open shared object file: No such file or directory) libGL error: unable to load driver: amdgpu_dri.so libGL error: driver pointer missing libGL error: failed to load driver: amdgpu libGL: OpenDriver: trying /usr/lib64/dri/tls/swrast_dri.so libGL: OpenDriver: trying /usr/lib64/dri/swrast_dri.so libGL: Can't open configuration file /home/user/.drirc: No such file or directory. libGL: Can't open configuration file /home/user/.drirc: No such file or directory.

That sounds a lot like the issue here: https://forums.gentoo.org/viewtopic-p-7662734.html Check your grsec settings or other permission problems.
Regarding the line "MESA-LOADER: could not create udev device for fd 4" I agree, but I don't think that's the problem here. amdgpu_dri.so doesn't exist anywhere on the system and afaiu running glxgears as user mesa should try to load radeonsi_dri.so instead of amdgpu_dri.so, just like it does when run as root (at least that's the impression I got from my research on the web, though right now I can't provide any sources - as soon as I find anything I will report it here). Using the kernel with CONFIG_EXTRA_FIRMWARE="radeon/kaveri_ce.bin radeon/kaveri_me.bin radeon/kaveri_mec2.bin radeon/kaveri_mec.bin radeon/kaveri_pfp.bin radeon/kaveri_rlc.bin radeon/kaveri_sdma1.bin radeon/kaveri_sdma.bin radeon/kaveri_uvd.bin radeon/kaveri_vce.bin radeon/BONAIRE_uvd.bin radeon/BONAIRE_vce.bin" CONFIG_DRM_RADEON=y CONFIG_DRM_RADEON_USERPTR=y CONFIG_HSA_AMD=y # CONFIG_DRM_AMDGPU is not set I don't experience the described problem, despite glxgears also complaining about not being able to create udev device: $ LIBGL_DEBUG="verbose" glxgears MESA-LOADER: could not create udev device for fd 4 libGL: OpenDriver: trying /usr/lib64/dri/tls/radeonsi_dri.so libGL: OpenDriver: trying /usr/lib64/dri/radeonsi_dri.so MESA-LOADER: could not create udev device for fd 4 libGL: Can't open configuration file /home/user/.drirc: No such file or directory. libGL: Can't open configuration file /home/user/.drirc: No such file or directory. libGL: Using DRI2 for screen 0 Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. With the latter DRM_RADEON-kernel kwin works with opengl and supertuxkart works, I don't run into this bug: https://bugs.archlinux.org/task/40807#comment133021 and vaapi and vdpau work in contrast to the DRM_AMDGPU-kernel.
http://xorg.freedesktop.org/wiki/RadeonFeature Afaiu radeonsi is the 3D driver which is needed for accelerated 2D (glamor) and thus should be loaded here.
I've never heard of a problem like this. There's no amdgpu_dri.so driver in Mesa... I figure that's part of the proprietary driver package. Can you still reproduce this with current stable?
