Ok, fixed. With -a4k is it now booting. Looks like the partitions weren’t aligned!

As to whether they ought to be aligned by default, this box is on a slightly older version:

  10.0-RELEASE-p7 FreeBSD 10.0-RELEASE-p7 #0: Tue Jul  8 06:37:44 UTC 2014

so perhaps that’s been fixed since.

Many thanks folk for your help!

Cheers,
Joe
