Kernel panic on amd A8 Apu Radeon 7 is there anything i can do ?
I'm out of gpu because it was too old i guess and until my new
arrives i want to use
the integrated gpu but i can't
I tried also the current without any luck
On linux to select the amdgpu driver instead of radeon i had to enter
these parameters
radeon.cik_support=0 amdgpu.cik_support=1
Any way i can pass these parameters on the module or something.
I got either kernel panic or a message that says it can't load kaveri
firmware
and then kernel panic
I have installed the gpufw firmware but still no luck
Any help would be appreciated and sorry for bothering you.

It sounds like you've hit an issue where the specific firmware files
needed for your GPU aren't installed by NetBSD. This is likely the same
as this PR:
http://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=54976

I also had this problem with similar hardware, and solved it simply by
manually installing all the files found in kernel.org's linux-firmware
tree for Radeon:

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/radeon

You probably already know this, but you can download full snapshots of
linux-firmware like this:

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/snapshot/linux-firmware-20220411.tar.gz

Then place the Radeon files at /libdata/firmware/radeon. Basically, you
probably need some of the files with lowercase names, rather than the
uppercase versions.

You shouldn't need most of them, but I don't know the full gamut of the
files you may need, so it's simpler to just add them all.

I hope this helps. If not, you may want to file a PR, as it's something
different.

Regards,

Dave
