Ok, another observation: I was using qemu from sources from the other day:
v2.0.0-1806-g2b5b7ae917e8
Switching back to the installed one:
$ qemu-system-x86_64 --version
QEMU emulator version 1.7.1 (Debian 1.7.0+dfsg-6), Copyright (c) 2003-2008 Fabrice Bellard
fixes the issue.
Joerg says I should bisect but I'm busy with other stuff. If people are
interested in chasing this further, I could free up some time to do
so...
