FS#176 - Disapearing radios for ath9k introduced between August 31 and September 4th

Okay, I tested r1600 and it is still broken, I lost both radios by simply moving my nexus5X into the next room.
The diagnostic messages are slightly different but the result is the same, the radios disappeared, and issueing "wifi" on the router's CLI will bring them back temporarily.
I assume that going back to figuring out which commit introduced that behavior is the best course of action right now.
