Testing plan is not complete
This is a 4.6 merge
What about master?

[andyp1per]

The vendor has done the testing, this is the same problem that TBS ran into which we fixed in the code but didn't rebuild all the bootloaders. This just rebuilds the bootloaders on 4.6. We should probably rebuild all of the bootloaders on 4.6 as well if we haven't already done so.

ITYM 4.7?
