Greg, the backtrace says the crash happened here: 0x4008f6de is in vTaskEnterCritical (/Users/mark/esp/esp-idf/components/freertos/include/freertos/portmacro.h:283). 278 * Warning: From the ISA docs: in some (unspecified) cases, the s32c1i instruction may return the 279 * *bitwise inverse* of the old mem if the mem wasn't written.

Can you verify my assumption?
Looks like an init race condition, i.e. m_rxqueue used in undefined state.

Just noticed this on my production 3.1 module. Was this an artifact of the upgrade from .005 to .006?
