Yeah, I logged a bug in the lshw tracking system (which is moderated,
so it's not publicly visible yet). I also intend to raise it on
bugs.debian.org (Jessie can still crash the Mustang boards, and I'm
thinking the powerpc port will also be potentially risky).

I don't mind, but as always I am slightly unsure of what level of
severity I should raise it at.
