I upgraded gentoo-sources from 5.15.147 to 5.15.151 this morning and amdgpu support is now borked on my system with an AMD Ryzen 5 3400G with Radeon Vega Graphics.
Everything worked fine with 5.15.147, but when 5.15.151 (built with same .config via "make oldconfig") boots there's always a kernel oops, and video output goes blank. I suppose maybe it's time to see if 6.1 works... [ 2.888353] [drm] amdgpu kernel modesetting enabled.
