Just a point of clarification, I think you=E2=80=99re mixing version =
numbers up a bit: the Linux kernel version discussed in that forum =
refers to kernel 4.19 (released Oct 22, 2018), not 1.19. The =E2=80=9Ccomp=
iled for 1.18.4=E2=80=9D line is referring to the Xorg server version, =
not a Linux kernel version (there never was a Linux kernel 1.18, it =
jumped from patches against 1.0 to 1.1.x versions around ~April-May =
1994.

Depending on where your amdgpu module came from (e.g., if you compiled =
it yourself), the first thing I=E2=80=99d verify as a starter is that =
the =E2=80=9Ccompiled for=E2=80=9D version actually matches the Xorg =
server version you have installed via packages/ports/etc.


Thanks,
