Just a point of clarification, I think you’re 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 “compiled for 1.18.4” 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’d verify as a starter is that the “compiled for” version actually matches the Xorg server version you have installed via packages/ports/etc.
