I tried it on kernel 5.3-rc1 and the previous mesa-git release. havent updated today yet though. these were my results: Manjaro won’t boot with Radeon 5700XT
I'll keep you guys updated. Don't have a second GPU though- currently running an APU- so I can't test the Ryzen 3700X until the RX5700XT works. From what I've heard it's having a lot fewer issues though.
