Please check if commit bb1d132935c2 ("drm/i915/vbt: split out defaults that are set when there is no VBT") fixes things for you.
I think this is not going to help. This would only make a difference when there is no VBT at all at which point we would see this message in the logs:
DRM_INFO("Failed to find VBIOS tables (VBT)\n");
but in this case we have a VBT for ports B, C and E.
[drm:intel_bios_init [i915]] Port B VBT info: DP:1 HDMI:1 DVI:1 EDP:0 CRT:0 [drm:intel_bios_init [i915]] VBT HDMI level shift for port B: 8 [drm:intel_bios_init [i915]] Port C VBT info: DP:0 HDMI:1 DVI:1 EDP:0 CRT:0 [drm:intel_bios_init [i915]] VBT HDMI level shift for port C: 8 [drm:intel_bios_init [i915]] Port E VBT info: DP:1 HDMI:0 DVI:0 EDP:0 CRT:0 [drm:intel_bios_init [i915]] VBT HDMI level shift for port E: 0
Let me know if I'm missing something and we will test it anyway
Thanks Daniel
