One of Anton's VSX patches hasn't landed in master yet and is still queued in ppc-for-4.1: "target/ppc: Fix lxvw4x, lxvh8x and lxvb16x". Can you try David's ppc-for-4.1 branch first and let me know if that solves the issue? If not, I'll take a look at it later in the week when I have a bit more time. ATB, Mark.
