Description
Hi, I've been working with Apple support on this one as it involves a new 2017 MacBook Pro with Touchbar. When the Mac is plugged into an external monitor and Keybase is installed, 50%+ of the time I attempt to log out, restart or shut down the computer I get an indefinite black screen and a screaming fan. The only way to stop it is to hold the power button to force it to shut down. Upon restart, my Console System Reports are filled with Kernel gpuRestarts like this:

It seems like this could be a Mac bug, but I certainly don't know enough about it to say that for certain.

Research direction
The report names no repository files, tests, or entry points to inspect. Begin by reproducing the logout, restart, or shutdown failure on a 2017 MacBook Pro with Touch Bar, an external monitor, and macOS 10.12.6, then compare Console GPU restart reports; done means the black screen and associated GPU resets no longer occur.
