So the > problem is specific to ZFS root. Now I think I know what is the source of problem. After all, on 13.0-RELEASE i386 system simply loading zfs module results in system hang up. The steps to reproduce it are, 1. Boot with install media of 13.0-RELEASE i386 2. At the first menu of FreeBSD installer, select 'Shell'. 3. At the shell prompt, type `kldload zfs` and return key. I confirmed hangup happens with VirtualBox, VMware Player and my bare metal PC environement. So the problem doesn't depend on hardware. And hangup also happens with 13-STABLE and 14-CURRENT. --- Yasuhiro Kimura
