It's hard to guess what's going on with a description of "messages
like..." rather than the actual messages verbatim.  But if I had to
guess at this point, I'd lean towards a difference between SATA devices
being "ad0" and "ada0" which might be different between target systems
based on the BIOS settings on each system for whether to present the
drives as legacy/compatible IDE versus AHCI.  The options used to build
the kernel also have some effect on ad0 vs ada0, but I'll admit to being
in a complete state of confusion over that because of working on systems
using 8.x, 9.x and 10.0 every day, and I've completely lost track of
what behaviors are seen in which versions.
