    Kernel 4.20.3 & .4 breaks laptop video with Raven Ridge 2500U

    The older kernels work well (enough), but the new 4.20 series have so far left the system booting to scrambled graphics where the log-in screen should be. It seems whatever fixes have been introduced for Raven Ridge have had the opposite effect on this system, which is a Dell Inspiron 5575. The chip is a Ryzen 5 2500U.

    Is there some kind of fix I can implement for these kernels, or do I just need to wait for an official patch to land? I hope the devs are aware of the issue, at any rate.

    Sounds good. I have an incomplete desktop Raven Ridge system around, but I'm not too thrilled to get it out and get it going just to test this. No idea what differences exist between such a home brew desktop system and a laptop.
