Ah, ok.  Please attach full "dmesg" output from booting.

I guess I'd suggest "apt-get reinstall firmware-linux-nonfree", although
since ...

What package does "dpkg-query -S /lib/firmware/3.2.0-rc7" indicate is
responsible for those?

Luckily I imagine udev can cope without being too distracted by such
things. :)

Not related, but you can fix this with

	echo 'APT::Default-Release "sid";' >/etc/apt/apt.conf.d/80vp-prefers-sid

See apt.conf(5) and /usr/share/doc/apt/examples/configure-index.gz for
details.

Thanks again.
