I never met a pleasant one :-)

Right, panicked.

No it shouldn't panic anyway.

Can you open a Trac bug about this, just cut and paste your description
here is fine.

If we can reproduce it with a debug board it's probably not too hard to
make the panic go away anyway.

Ad-hoc is relatively uncommon so it makes sense it's going to show more
bugs.
