Still happening with latest upstream kernel. It seems to involve using the -initrd option at all, with any cpio file, even a tiny one. More results posted here:

Literally after the virtio_mmio.ko and virtio_scsi.ko modules are loaded, there are no messages about disks, and of course nothing else works.

Worked with kernel 3.16 so I suspect this could be a kernel bug rather than a qemu bug, but I've no idea where to report those.
