[indiana-discuss] build 100 image-update: cannot boot to previous BEs

[Sebastien Roy]

After an image-update to build 100, I can no longer boot to my previous
boot environments.  The system successfully boots into build 100, but my
build <= 99 boot environments all crash when mounting zfs root like this
(pardon the lack of a more detailed stack, I scribbled this on a piece
of paper):

<garbage address>
mutex_owner_running()
lookuppnat()
vn_removeat()
vn_remove()
zfs'spa_config_write()
zfs'spa_config_sync()
zfs'spa_open_common()
zfs'spa_open()
zfs'dsl_dlobj_to_dsname()
zfs'zfs_parse_bootfs()
zfs'zfs_mountroot()
rootconf()
vfs_mountroot()
main()
_locore_start()
