            Bug ID: 93522
           Summary: Tonga has only black virtual terminals
           Product: DRI
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: EoD@xmw.de

When I boot the kernel via grub everything is fine, once the kernel is loading
there is only a black screen until X starts.

When I switch back to the VT (via Ctrl+Alt+F1) I still see everything from X,
except the mouse. When I switch back to X everything works fine again.

I am using current mesa-git and kernel 4.4-rc6.

glxinfo, dmesg, etc: can be found here:

Make sure you compiled drm fbdev support into your kernel and that the fbcon
support is loaded (either built into the kernel or the module is loaded).

Are you referring to DRM_FBDEV_EMULATION?

Yes, that needs to be enabled.
