So unknown connection is only reported for DP if the structure does not
match one of the known registers. Sounds like we bailed during
initialisation, but after hooking the structure into the drm connector
list.

Which does not seem likely given that we only fail intel_dp_init for the
memory allocation failure at the start. Some other form of memory
corruption or bogosity?

Tools to use? memtest86? memory_corruption_check_size=?

The starting point would be to add drm.debug=0xf to your boot line and
lets have a close look at what is going on during boot + discovery [dmesg].
