amdgpu causes kernel panic on load with Radeon 860M iGPU

I installed FreeBSD 15.0-RELEASE-p2 on a Lenovo Ideapad Slim 5 laptop, with a AMD Ryzen AI 7 350 CPU and Radeon 860M iGPU. When running kldload amdgpu I get a kernel panic like this

Code:

I've tried the driver with pkg versions of drm-515-kmod, drm-61-kmod, drm-66-kmod, and drm-latest-kmod (6.9) and also the ports versions of drm-61-kmod, drm-66-kmod, and drm-latest-kmod. Fwget didn't find any gpu firmware I didn't already have.

I suspect I'm simply missing a piece of firmware needed, but I have no idea what it is. Thanks in advance
 
If you have access to a recent linux livecd, try to check which firmware files are loaded there. I'm guessing the firmware needed for your graphics card was added/updated in the last year.

I did that looking at dmesg | grep amdgpu on a manjaro live cd and all of them seemed to already have been installed on my freebsd system. The issue still remains.
 
Kierteiyu , if you want to try a newer package with updated files.

Checkout, https://github.com/freebsd/freebsd-ports/tree/main/graphics/gpu-firmware-amd-kmod and replace the attached files. You can then build with:

# cd /usr/ports/graphics/gpu-firmware-amd-kmod/
# for FLV in $(make -V FLAVORS); do make package FLAVOR=${FLV}; done

And install with:

# for dir in work-*; do pkg install -y -f $dir/pkg/*.pkg; done

PS: Or use poudiere.

Otherwise, the drm 6.10 PR was approved last week. I'm guessing it will reach at least STABLE soonish and you can try again.

The DRM 6.10 kmod requires a newer kernel (FreeBSD-CURRENT). I tried the development version of FreeBSD 15, but it's not supported there yet.

Probably the only thing you can do is try building the tagged drm-610_1-kmod against FreeBSD-CURRENT or wait until it gets a release version.
 
drm-kmod currently 515/61/66 (from linux kernel lts)?
based on https://github.com/freebsd/drm-kmod/ tags there are 6.(7,8,9,10), so not lts?

i haven't had any luck finding the exact firmware bin (with linux) but MIGHT be gpu-firmware-amd-kmod-gc-11-5-2-20250808.pkg

gmc_v11_0.c could be that code, but yet 11.5.2 are missing, so will wait for 6.11/6.12lts

i still think its weird it uses non lts

ubuntu 24.04.2 6.8: amdgpu: fatal error during GPU init
edeavouros endeavour 6.10: amdgpu: fatal error during GPU init
ubuntu 24.04.3 6.11: amdgpu works
