Hi-
I can add that I tested your patches on a 9.3 Stable machine.
The motherboard is a GA-Z77-D3H (rev. 1.1) with onboard Atheros AR816x.
I did have to apply one of the patch hunks by hand, see below.
I am able to ssh into the machine, and remotely access apache/poudriere.
I have not seen any problems so far.
I've included a few outputs for you to examine.
