Not sure if it's the same ?
The point is that the I get the messgaes
   Trying to mount root from zfs:tank/root
and the mountroot> prompt
BEFORE the following messages
   ZFS filesystem version 6
   ZFS storage pool version 6

If I enter : zfs:system at the prompt, it boots allright.
On occasions, booting in verbose mode, I got the "version 6" messages before
trying to mount root, and then everything just works fine.
It's not the case since my last buildworld though :(
