These messages: [ 5.790660] [drm:intel_dsi_vbt_exec_sequence [i915]] Starting MIPI sequence 1 - MIPI_SEQ_DEASSERT_RESET [ 5.790753] [drm:intel_dsi_reset_clocks [i915]] [ 5.790853] [drm:intel_dsi_reset_clocks [i915]] [ 5.801010] [drm:intel_dsi_reset_clocks [i915]] [ 5.801113] [drm:intel_dsi_reset_clocks [i915]] [ 5.901621] [drm:intel_dsi_reset_clocks [i915]] [ 5.901723] [drm:intel_dsi_reset_clocks [i915]] Should show something else for the ntel_dsi_reset_clocks lines. This typically happens if you make some changes and try to speed things up by using make modules M=drivers/gpu/drm/i915 to speed up building. For some reason this confuses the code injecting the function names in the debug logging. Can you retry with a clean kernel build and attach a new log ?
