It was hard to catch the dmesg and Xorg log because soon as I close the Dolphin emu the system hard freezes --> no data synced. Note that after the kernel prints those last lines the the bug is just triggered - after I close the Dolphin main window does the crash occurs.
If some one is interested I have kdump data of the system. Thanks to my kexec dump kernel. :)

--- Comment #4 from JATothrim jarmo.tiitto@gmail.com --- Created attachment 117555 --> https://bugs.freedesktop.org/attachment.cgi?id=117555&action=edit Maybe fix?
I searched Vanilla kernel git logs/patches and found this patch. I hope it could fix the kernel crash on kernel 3.18.x series. I'm testing the patch now.

--- Comment #5 from JATothrim jarmo.tiitto@gmail.com --- I did more research and I was able to capture full kernel crash dump.
Debugging the crashdump I found that The kernel dies at kernel version v3.18.19 in src lines: drivers/gpu/drm/radeon/radeon_mn.c:75 or drivers/gpu/drm/radeon/radeon_mn.c:76 on to NULL ptr dereference. At both code lines the kernel tries to lock a mutex apparently. I don't know exactly which one fails as I'm no expert debugging x86-64 assembly.

--- Comment #6 from Christian König deathsimple@vodafone.de --- Well have you tested this with the current upstream kernel? E.g. 4.1 or a recent rc of 4.2?
That's usually the first thing you should to to figure out if newer kernels are already fixed.

Phew. I finally managed to compile/test newer kernel v4.2 and this bug is fixed! :) Yay! My tip for radeon 7870 owners: if your screen freezes and turns into a weird rainbow mess try kernel v4.2.
