dmesg output since usermode crash that caused bug

When a user-mode program crashes while using amdgpu resources amdgpu fails to
pin userptr then segfaults in the GPU scheduler. This occured while attempting
to port a program to use Wayland and Vulkan on AMD Ryzen 3700X and AMD RX580
using unmodified amdgpu drivers.
