After booting into it run dd if=/dev/random of=/tmp/dump bs=16384 and press reset button. Repeat the unexpected reset condition until the issue will appeared. In my case there was several attempts before reach the state. The issue was initially discovered from the real running hardware. >Fix: There is no known fix, but some workaround. Boot into any FreeBSD livecd and kldload geom_mirror kldload geom_journal After the message GEOM_JOURNAL: Journal mirror/vol0a consistent will appear reboot back from HDD. >Release-Note: >Audit-Trail: >Unformatted:
