Hello, When I am running with 4k stacks enabled, my kernel completely locks up when I get a high load. When I am running with 4k stacks disabled, my kernel runs stabely. From the few kernel output I can get on the serial port, I see some type of recursive kernel fault. Is there a way to get a stacktrace in this case so we can identify which execution path is causing this stack overflos ? Attached is the output form the serial port which shows some type of recursive kernel fault.
