The following revision refers to this bug: https://chromium.googlesource.com/chromiumos/third_party/kernel/+/03fd4eaa9a4fdd071ddaceae608a6412055b6df4 commit 03fd4eaa9a4fdd071ddaceae608a6412055b6df4 Author: Kirtika Ruchandani <kirtika@chromium.org> Date: Sat Mar 04 02:40:23 2017 Revert "CHROMIUM: iwl7000: chromeOS: fix Intel regulatory (de)registration" This reverts commit b4803ed63478. It caused the wifi driver to get into a reboot loop, which brought down shill since no wifi interface was present, implying no network connectivity (since ethernet/cellular need shill too atm) for 4.4 based boards.

How super annoying, sorry about that. I don't (yet) see the reason for this, but can we keep the code move and just revert the #ifdefs? That way at least we keep the fix for the other bug.

Marking as fixed. Aashutosh/Debayan - can either of you help verify?

Network (WiFi n Ethernet) working as expected. Tested on Snappy & Electro R58-9337.0.0. Closing this as verified. Will reopen, if I see any issues on 9334.1.0 branch build (Not available yet for testing)
