Some more findings: Aside from only happening on reboot, but not shutdown, it also seems to only happen with i6300esb. Switching the qemu config to use ib700 instead of i6300esb, I am not able to trigger the problem. This confirm's Peter's findings who was not able to reproduce it on real hardware. I wonder, if this is a qemu issue, after all? CCing our Debian qemu maintainer. Maybe he has some insight on this matter (the complete bug log is at [1]).
