Then it completed successfully with 8GB memory. Additionally GENERIC kernel recognizes 8GB of memory.

Loading zfs module results in hangup on i386 (Re: Install of 13.0-RELEASE i386 with ZFS root hangs up)

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 ___ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
