I do:

mv /boot/Menu.rc /boot/menu.rc

and reboot.

The /boot/menu.rc can be read by zfsloader so I conclude that it was the 
directory entry of /boot/menu.rc thas has a problem in the first place.

Next time it happen I will directly use zfsboottest before any update to 
the pool.

Thank for your time!
