Created attachment 748134 [details] kernel dmesg (kernel 5.15, AMD FX-8370) with CONFIG_MBULLDOZER=y Current sys-kernel/gentoo-sources-5.15.0 builds fine with CONFIG_MPILEDRIVER=y on my AMD FX-8370 but it won't boot. I don't even get netconsole output... Does not matter whether I build the kernel with gcc or clang. But I found out when I build the kernel with CONFIG_GENERIC_CPU=y or CONFIG_MBULLDOZER=y it just runs fine. gentoo-sources-5.14.x are ok with CONFIG_MPILEDRIVER=y so I think it's a regression. Can anyone confirm this?
