The forum is not the spot for bug reports... There's bugs.openwrt.org or (in case of upstream projects like these) the project's bugtracker:

MT7612EN Constant hardware restart requested on b22977c

When this happens, all wifi traffic stops for multiple seconds while the hardwar…e restarts Chip: MT7612EN Device: Xiaomi MiWiFi 4A gigabit edition Using three of these devices as AP-repeaters with the backhaul on the same radio in WDS mode. All three are experiencing the same issue to differing degrees, some only have the message printed once per hour, others multiple times per minute. Frequency seems to depend on how many clients are connected and active. The device the log below was from a quiet AP with only 2 clients connected. If it matters, the other side of the backhaul is an Archer C7 v2 with a QCA9880-BR4A radio. All of the devices are running the latest OpenWrt snapshot which is using this master branch at commit ID b22977c Dmesg output follows: ``` [ 1105.247542] mt76x2e 0000:01:00.0: Firmware Version: 0.0.00 [ 1105.253078] mt76x2e 0000:01:00.0: Build: 1 [ 1105.257250] mt76x2e 0000:01:00.0: Build Time: 201507311614____ [ 1105.278354] mt76x2e 0000:01:00.0: Firmware running!
