Everything should match: * i386 arch, * `make installkernel`, * RELENG_8 after zfs v14 import, * zpool with zfs v14, * zfsboot installed. Boot partition is NOT compressed, changing the boot partition does nothing, even creating a new one. After that sometimes part of kernel or other modules would yield "ZFS: gang block detected" on loading. >How-To-Repeat: Any installkernel can do the trick. >Fix: Bootability can be restored with: rsync -lrptygoWSH --delete /boot /somewhere/boot rm -rf /boot rsync -lrptygoWSH --delete /somewhere/boot /boot >Release-Note: >Audit-Trail: >Unformatted:
