> Going by my memory here: It fails to boot with "ROOT MOUNT ERROR". I had luck with `zpool clear, removing disk1, and mounting all pool partitions. Data could be copied off but some filesystems were missing and attempts to list all snapshots segfaults. Every export/import requires a zpool clear. Attempting a scrub lead to a panic on every import on the pool thereafter. Tried a -current snapshot (FreeBSD-9.0-CURRENT-201105-amd64-dvd1.iso) livecd mode with similar panic results to 8.2-release.
Perhaps you should try to use
zpool import -F zroot
from an ZFS v28 system, such as the FreeBSD-9.0-CURRENT you mentioned?
