Damn, had sparse disabled for the test builds.  [ Too bad there are way
too many warnings on a full kernel build so having sparse enabled all
the time doesn't fly. ]

So this doesn't work either.

Hmm, back to using "u32" in the virtio config structs?

cheers,

Weird.
Let me try this and figure out what the issue is.
