Thank you for the patch, I have tested it with both drm-current-kmod and
drm-devel-kmod.
It did not make drm-current-kmod fail, but it did not help drm-devel-kmod.
The attach messages end thusly:
[drm] Connector 2:
[drm] DVI-I-1
[drm] HPD2
[drm] DDC: 0x1958 0x1958 0x1959 0x1959 0x195a 0x195a 0x195b 0x195b
[drm] Encoders:
[drm] DFP3: INTERNAL_UNIPHY
[drm] CRT1: INTERNAL_KLDSCP_DAC1
drmn0: [drm] Cannot find any crtc or sizes
drmn0: [drm] Cannot find any crtc or sizes
drmn0: [drm] Cannot find any crtc or sizes
sysctl_warn_reuse: can't re-use a leaf (hw.dri.debug)!
[drm] Initialized amdgpu 3.37.0 20150101 for drmn0 on minor 0
The sysctl re-use warning is new, but the drmn0 lines are unchanged compared to
the kernel without this patch.
