maybe best thing to do is to split that
With this and the previous patch the stack traces are gone.
maybe not the perfect fix though... can you share how you're starting

drm.debug=0xe param.
In theory 5a9d38b20a5a ("drm/i915/display: hide workaround for broken vbt in intel_bios.c")
should filter out the PORT_F in KBL.
