I have not for two reasons.

1. As Christoffer mentions, the _k firmware only seems good for the 390X

2. I'm unfamiliar with the process of doing such and the steps for doing it are
spread across 100+ comments with no real sign of what steps are the right ones.

Still, these issues make using an 390 or 390X on Linux a nightmare. This issue
isn't "minor" and its importance rating should reflect that. This is a major
(or even critical) bug report, IMO.

One that has been open for 10 months, I might add.
