SMP FreeRTOS uses a single kernel lock for all critical sections. There is a known issue with esp_ipc_isr_stall_other_cpu() that can cause dead if the other CPU is already in a critical section. This commit adds a temporary workaround to reduce the chance of deadlock by taking the SMP FreeRTOS kernel lock first before stalling the other CPU. See IDF-5257 for more details.
