Crash with radeonkms

Sat Jan 14 06:43:29 UTC 2017

Hi, some updates on testing radeon drivers:

I can kldload radeonkms, amdgpu, and i915 now without crashing.

amdgpu and i915 cannot find the device, but symbols are being resolved (it's a radeon 2400xt)

radeonkms from drm-next+patch does load and find the device, but the screen goes dark immediately. Not sure what's the problem.
On my system which has an r600 chip it needs three firmware modules which are loaded correctly (or at least the right ones seem to have been loaded):
radeonkmsfw_RV610_me.ko
radeonkmsfw_RV610_pfp.ko
radeonkmsfw_R600_rlc.ko
radeonkms.ko

Further messages from radeonkms below (in case they are useful). I have a copy of the install kernel from CURRENT on the test machine which is able to load the stock radeonkms and the video switches to a hi-res text mode, so the stock radeonkms is working fine. I have another identical machine running 10.3 where X works fine so this is expected I guess. In all cases the same three firmware modules are loaded (drm-next, CURRENT, 10.3).

Messages from the patched drm-next radeonkms (screen goes dark):
