Since upgrading the server to 9-STABLE (2013-03-30) the gptzfsboot error =
message miraculously disappeared.

Because I upgraded the zpools on this particular server to a new version =
("feature flags") I cannot boot back to 9.1-REL to find out if the =
upgrade was the cause of this - or not.

When I bootup the server from a 9.1-REL USB stick, I also cannot =
reproduce the error.

What did I change since seeing the error message the first time?

- I put GPT partitions on da2-da7 and used them for zpools
- Upgrading 9.1 REL to 9.1-2013-03-30
- refreshed the zfs bootcode on da0/da1 aferwards

If the error shows up again on a similar server soon to be upgraded, =
I'll give feedback.
