No drm.debug=0xe module parameter in the dmesg. Please reproduce with that.

There's 

[  155.953639] [drm:drm_edid_block_valid] *ERROR* EDID checksum is invalid,
remainder is 192

in the logs, might explain things, but we have no details now.

> Kernel: (drm-intel-nightly) 64fcdb139972db2663469d8799968260fb43a26d
...
> It works well on -testing(54b927ca040f2adee35f9ee95c9ce40d6be2f0e8)

Could you bisect this please?
