• Device: ZBT-WG3526
• Software versions of LEDE release: right now running LEDE Reboot 17.01.0 r3205-59508e3 / LuCI lede-17.01 branch (git-17.051.53299-a100738), but problem was the same with previous rc
• It happens every few hours, some times reboots the router.
• As someone told me that the Wifi drivers are not stable, I disabled both, but the problem is still the same. When they were enabled, it was clear from the dump that the WiFi drivers were the cause, but not anymore.

I don't know how to interpret this, probably a developer will be able to identify the root of the problem, if some specific package, etc.
