If you don't mind too much, as this crosses two trees, I would prefer
to keep the series "self-contained" if people want to test.
Additionally, I have two Acked-bys for 9 and 10 from Andrew that are
not part of the patches yet.

Even without reinstalling, can you please have a look if your
"plug:green:health" LED is really green (mine is blue)?  And if your
kernel already has a "plug:red:misc" LED could you verify whether it
is really there?  Do you happen to know which board revision you
have?


Thanks,
