--- 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.
