Experiences regarding switch to #NetBSD - installation 10.1 goes okay, but AMD GPU (RX 5*0) does not work out of box. What I tried so far?
(1) Loading amdgpu and drmkms_sched kernel modules cause kernel panic.
(2) Setting up modesetting in Xorg causes "No screens found" error.
(3) Installing 11 RC4 does not go well - if I use MBR scheme then OS does not load at all, if GPT then installer fails at gpt create command.
(4) I tried to follow this guide - https://codeberg.org/blackmirroxx/netbsd_amdgpu - but I run out of space in /usr (separate partition) during compiling modular xorg.

Tomorrow I am going to install 10.1 again and follow above guide again. If it will not work, then...I do not know.

BTW OpenBSD advantage is that AMD GPU works out of box, disadvantage is "mediocre" support of non-FFS file systems.
