15.1-RELEASE drm-kmod kernel panic / black screen with amdgpu / radeonkms (AMD E2-6110)

[vedran]

Thanks, yes I am aware of drm-612-kmod-6.12.85.1501502_1 and thats what I installed. I'm on 15.1-RELEASE so I don't think getting the latest (i.e those with the tag 1501502) works. I am not sure what those are built for.

Since the radeon firmware + drm-612-kmod from ports did not work, I tried to build and install the amdgpu firmware (gpu-firmware-amd-kmod-mullins) and running kldload has the same result as in the original post:

drmn0: <drmn> on vgapci0
vgapci0: child drmn0 requested pci_enable_io
vgapci0: child drmn0 requested pci_enable_io
<6>[drm] Initalizing kernel modesetting (MULLINS 0x1002:0x9852 0x1025:0x0865 0x00).
<6>[drm] register mmio base: 0XF0C00000
<6>[drm] register mmio size: 262144

It freezes.

I have another Mullins and it worked the last time I tried it, both with radeonkms and amdgpu. Long shot, but do you have the latest system BIOS version installed?
