dmesg log from loading driver to blender start

Hello,

Starting the blender 2.81 on x86-64, xorg 1.20.5 and kernel 5.3.0-rc6-next will
cause a GPU lockup error (freeze, and after timeout GPU softreset).

Similar observation was made on mipsel debian sid (default blender and xorg
version, 5.3.0-rc6-next kernel) and mipsel buildroot (git snapshot blender,
last stable xorg, 5.3.0-rc6-next kernel).
