This commit breaks boot for me. The kernel can't open the zroot pool, leading to the familiar mountroot> prompt. And in a UFS-root VM, I can't load the ZFS kernel module. It fails with: link_elf_obj: symbol zfs_sha512_transform_sha512ext undefined linker_load_file: /boot/kernel/zfs.ko - unsupported file type On both systems, the CPU is a Ryzen 9 5950X, which does not support AVX-512. Could we please revert the change for now?
