Upgraded the bootloader in Fixit prompt to allow booting from v15 pool. After this, the system fails to boot, and freezes after the "Boot: F1" prompt with "-" on the screen. See this thread for example screenshot: MBR is used because of BIOS incompatibility with GPT as installed by FreeBSD. >How-To-Repeat: Set up root-on-ZFS in MBR slice on 8.2-RELEASE according to: Reboot - system halts on "-". >Fix: Install zfsboot from 9.0-BETA2, where the problem is fixed. >Release-Note: >Audit-Trail: >Unformatted:
