Problem upgrading FreeBSD 10

[Ricardo Campos Passanezi]

Hello all.

Back in september I've installed a "current" (it was a FreeBSD 10,
r2552041). The system is working fine.

I've returned this week from a vacation and tried to upgrade to
stable/10 with no success. The machine is running a zfs-mirror:

# zpool status

After building work and kernel for a
"svn://svn.freebsd.org/base/stable/10", apparently the system stops at
(or imediatly after):

ZFS filesystem version: 5
ZFS storage pool version: features support (5000)

In the "/var/run/dmesg.boot" I have, among other lines:

Do I have to use svn://svn.freebsd.org/base/head only ???

I've tested with the above and the single user boot has worked fine...

Need more info?


TIA...
