They affect userspace in a way that breaks systemd opration: ... Freeing unused kernel image (initmem) memory: 1024K Run /sbin/init as init process systemd[1]: System time before build time, advancing clock. systemd[1]: Cannot be run in a chroot() environment. systemd[1]: Freezing execution. Reverting them on top of next-20220223 fixes the boot issue. Btw, those patches are not bisectable. The code at 30512d54fae354a2359a740b75a1451b68aa3807 doesn't compile.
