--- Comment #8 from Hans de Goede <jwrdegoede at fedoraproject.org> ---
Yes this is better, quoting the same bit from the log as before:

[    2.984008] [drm:intel_dsi_vbt_exec_sequence [i915]] Starting MIPI sequence
1 - MIPI_SEQ_DEASSERT_RESET
[    2.984230] [drm:mipi_exec_gpio [i915]] 
[    2.984457] [drm:mipi_exec_delay [i915]] 
[    2.994759] [drm:mipi_exec_gpio [i915]] 
[    2.994989] [drm:mipi_exec_delay [i915]] 
[

So now we can actually see what the MIPI sequences are doing (to some degree)
unfortunately everything looks normal and there is not really a clue there why
the panel stays black.
