I wouldn't be surprised if there's something oddball in my system config
that changes the situation.

Hmm.. I'd first have to figure out how to build a qemu image at all..

Full dmesg attached.  Had to piece it together from a 'dmesg' and what
got saved in pstore when it crashed.  I was surprised that the printk_once
popped during very early boot (2.88 seconds in), and then only 2 lines of output
right before the crash:
