@danj and @mattscheurich I'm also facing the issue. I have a 2K display attached to:

MBP mid 2015

Processor: 2.5 GHz Intel Core i7

Memory: 16 GB 1600 MHz DDR3

Graphics: AMD Radeon R9 M370X 2048 MB, Intel Iris Pro 1536 MB

The CPU goes bonkers and kernel_task remains at +400%. Unplugging the Dell 2K display immediately settles it down.

I'm using plain HDMI cable for the display, it's not a thunderbolt. I'm not sure how a damaged Thunderbolt chip can be a cause here because I'm using HDMI?
