(Radeon RX 6600 ) graphic works but only if do not add kernel module to /etc/rc.conf (is entry in rc.conf mandatory)

[grafi]

If I install pkg install drm-kmod and add sysrc kld_list+=radeonkms my graphic card stop working and freeze on following visible on a screen.
But if i remove radeon line from /etc/rc.conf then precede with pkg remove drm-kmod, followed by pkg install graphics/gpu-firmware-amd-kmod or go with port compillation cd /usr/ports/graphics/gpu-firmware-amd-kmod/ && make install clean everything works like charm. But if I try to add sysrc kld_list+=radeonkms everything goes south again.

The 1000000 $ question is, does drivers even works without proper entry in /etc/rc.conf
A clarification needed and will be greatly appreciated

I think you have to load the "amdgpu" instead of "radeonkms" module. Without any kmod there may be some frame buffer device involved, IDK.

I will check just that. One more little thing I've noticed that kmods have their respective names

• aldebaran: gpu-firmware-amd-kmod-aldebaran
• arcturus: gpu-firmware-amd-kmod-arcturus

so if it helps anybody gpu chip or name of gpu of Radeon RX 6600 is navi 23 https://www.techpowerup.com/gpu-specs/?mfgr=AMD&memsize=8 GB&sort=name

I would try amdgpu driver instead of radeon for that new card. If you don't # kldload anything and there are no entries in /etc/rc.conf, the driver won't be loaded.

Try installing graphics/drm-kmod metaport and try loading it.
# kldload amdgpu and see if it crashes.

I have this card and it works with amdgpu

No, X simply falls back to scfb(4) or vesa(4) depending on how the system booted (EUFI or CSM/BIOS). That's why it appears to work. You can check this by looking at /var/log/Xorg.0.log.
