On my case is is a severe bug preventing me from playing games on dolphin.
System: Linux Mint 17.3 using kernel 3.18.19 and oibaf graphics drivers ppa
100% reproducible in my system, happens always:
-Start dolphin 4.+ GCN emulator and play a minute e.g. Super Mario Sunshine.
-Close emulator window: kernel crashes soon after outputting 1-5 lines of:
Jul 31 22:43:47 kernel: [ 6008.091188] [drm:radeon_mn_invalidate_range_start]
*ERROR* (-1) failed to wait for user bo
Jul 31 22:43:47 kernel: [ 6008.092895] [drm:radeon_mn_invalidate_range_start]
*ERROR* (-1) failed to wait for user bo
inxi -Gxx output:

Xorg.0.log
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. :)
Created attachment 117555 [details] [review] 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.
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.
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.

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.
