This is still happening. It seems that these GPU need engine r=
esets before bus
reset, similar to what was done for Fury and Polaris, but more extensive.

Temporary workaround (yeah sure) is to eject the driver - rmmod in guest or
eject in Windows. This resets the engines.

Windows did the resets on shutdown until version 18.5.1 where they broke
shutdown sequence again - read release notes on Radeon Pro Vega FE drivers
where they actually slightly care.
