I tested with qemu 4.0, 4.1, and mainline (with my patch series applied on top

One problem I do see is that booting mainline (as of right now) is _slow_ 
compared
to released versions of qemu. It takes some 35 seconds to get to "Unpacking 
initramfs",
compared to ~8 seconds for v4.1 and earlier. Otherwise it works.

Hmm, slow compared to v4.1.0 ? That's not so long in the past so
that seems worth trying to bisect to find the culprit...


Yes, I know. I put it on my task list.
