I noticed my wireless interface can't get up with linux v4.14 and the
kernel log is flooded with firmware errors:
iwlwifi 0000:03:00.0: Firmware error during reconfiguration - reprobe!
iwlwifi 0000:03:00.0: FW error in SYNC CMD DQA_ENABLE_CMD
ieee80211 phy63: Hardware restart was requested.
The wireless controller is: Intel Corporation Wireless 7260 (rev 83)
Firmware used is: iwlwifi-7260-17
Everything works fine with v4.13.12.
I didn't have time today to bisect for the offending commit. Full log
