Can be verified, or has been verified? I want to know that someone has
done testing to confirm that the firmware fixes the crash, and will be
able to do so when this update is in -proposed. I don't care whether
that is you or someone else, but we don't do SRU updates based just on
the hope that it will fix a problem.
