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
here for me though so interesting it's different for you. I'll
investigate it and maybe just remove that test for now.

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.
