Oh you have a SPR failure too? I'll check that on a P9.

Yeah, that dispatch count after unregister test may be bogus actually.
PAPR doesn't specify what should happen in that case. It was working

These should be TCG errors. I have it passing them all with patches
posted to qemu lists. Very simple but effective way to catch a few
classes of errors.
