Hello group, I have compiled the lastest kernel and receive the following crash. The system crashes 2 to 3 time a day at random times. I have a 80211s mesh between two nodes running without encryption for testing purposes. the only message i get is below. Happens on Alix 3d3 board and commel 370 boards (amd/intel)
Anyone else see this issue?
