At some point I believe it was agreed that CI would test this
and get the new firmware automatically from the cover-letter.

The problem is that I don't see any cover-letter so I'm afraid
it is not running with the new firmware.

Tomi?

Also I believe in case it has the cover letter it should run
the full CI on the machine or at least stash it and run on
the weekend or whenever we run the full on all machines and
then report back again. Possible?

Martin?
