like Daniel guessed, fb-console does not work with this Patch.

i tried your Patch (additional patch for headerfile): https://github.com/frank-w/BPI-R2-4.14/commits/4.20-fbdev

and R2 hangs (no crash and no further boot)

[ 5.435075] mediatek-drm 14000000.dispsys: bound 14012000.rdma (ops mtk_disp)
[ 5.435134] mediatek-drm 14000000.dispsys: bound 14014000.dpi (ops mtk_dpi_c)
[ 5.459277] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
[ 5.465863] [drm] No driver support for vblank timestamp query.
[ 5.472331] [drm] Initialized mediatek 1.0.0 20150513 for 14000000.dispsys o0

my monitor is switched on, but no output....we had added fbdev-driver to get FB-console over hdmi, so it's currently useless
