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.

Can you try on 5.6 kernel. Fixes for userptr where submitted and merged into
that release and I think are lined up for 5.5.14

5.5.14 fixes this issue (though I can't use 5.6.1 for an unrelated bug) Thank
