Hard to say. It's probably just not reproducible every time, or
depends on factors that can't be easily controlled.
IMHO our best bet right now is try latest 9.0 snapshot, and if that's
still broken then try setting vfs.zfs.debug=1 and watch the output.

Yes. It's badly broken right now (for many different reasons), I'm
surprised he could finish the install too.
However kernels should operate on best-effort basis. If there's
enough information for other kfreebsd versions to boot, there should
be for 9.0 too.
