Hi,

i try to get hdmi running on bananapi-r2 with 5.1 but also without CK Hu's frambuffer-Patch i get no x-server working

my codebase: https://github.com/frank-w/BPI-R2-4.14/commits/5.1-hdmi
reused some Patches working on 5.0 (here X-server is working, but not fbcon)

WARNING: CPU: 2 PID: 895 at drivers/gpu/drm/drm_atomic_helper.c:1430 drm_atomic_helper_wait_for_vblanks.part.1+0x2a4/0x2a8

any hint how to fix this? if needed i can send full bootlog (with drm.debug=7)

regards Frank
