--- Comment #57 from Jani Nikula <jani.nikula at intel.com> ---
Miroslaw, please attach /sys/kernel/debug/dri/0/i915_vbt for each device type,
with display a and with display b.

The VBT contains display sequences to run at specific stages of display
control, including changing GPIO states. This probably conflicts with pin
control.
