I found the commit that is causing the problem (after three hours
of bisecting). That's the good news. The bad news is it isn't something
I can revert .. or easily fix, since the commit is large and is pretty
much tree wide. There's a lot of commits stacked on top if that change,
so it can't be reverted.

commit 82ed4db499b8598f16f8871261bff088d6b0597f

block: split scsi_request out of struct request
And require all drivers that want to support BLOCK_PC to allocate it
as the first thing of their private data. To support this the legacy
IDE and BSG code is switched to set cmd_size on their queues to let
the block layer allocate the additional space.

I was able to boot with the following in the command line:
-drive
file=tmp/deploy/images/qemux86-64/core-image-minimal-qemux86-64-20170822200708.iso,if=virtio,media=cdrom
--------
IMHO we need to stop using the ancient IDE support, since it continually
is broken (not usually this badly .. but often in more subtle ways).
So switching to a virtio backed CDROM, while the issue is reported
upstream is probably the best bet.
