--- Comment #11 from Bjoern A. Zeeb <bz@FreeBSD.org> ---
I had a similar issue with amdgpu on a FW16 which would go like:
kldload amdgpu
black screen
count to 5
See POST

No ddb, no kernel dump, ...  I tried 6.1, 6.6, and master at least from github
built along the kernel.

I thought it was switching to GENERIC-NODEBUG which made it work beginning of
October, but it seems it might have been putting linux-firmware.git for too
much wifi into /boot/firmware?

fwget -n says I should install:
gpu-firmware-amd-kmod-dcn-3-1-4
gpu-firmware-amd-kmod-gc-11-0-1
gpu-firmware-amd-kmod-psp-13-0-4
gpu-firmware-amd-kmod-sdma-6-0-1
gpu-firmware-amd-kmod-vcn-4-0-2

pkg-plist says for the file that did not load for cy@

% grep gc_11_0_1_mes pkg-plist 
%%GC_11_0_1%%/%%KMODDIR%%/amdgpu_gc_11_0_1_mes_bin.ko
%%GC_11_0_1%%/%%KMODDIR%%/amdgpu_gc_11_0_1_mes1_bin.ko
%%GC_11_0_1%%/%%KMODDIR%%/amdgpu_gc_11_0_1_mes_2_bin.ko

so if the plist is correct that should be there;  but the PCI ID for your card
may differ;  would be interesting to know?

If you do a bootverbose (boot -v) you will see more information about which
firmware files are being tried to load incl. the .ko files from /boot/kernel
and /boot/modules if there is no plain firmware file in /boot/firmware/ . The
latter is tried first.

If the problem is indeed that amdgpu make the kernel panic or even reset the
machine if it fails to laod firmware then the driver needs some improvements.
