I've been running my cbu-based devboard for a few days continuously and logging via serial. Log configuration:

bk72xx:
  board: cb2s
  framework:
    sdk_silent: "none"
    loglevel: VERBOSE
    options:
      LT_DEBUG_ALL: 1
      LT_DEBUG_WIFI: 1
      LT_DEBUG_MDNS: 1
      LT_DEBUG_LWIP: 1
      LT_DEBUG_OTA: 1
      LT_DEBUG_LWIP_ASSERT: 1
      LT_DEBUG_CLIENT: 1
      LT_DEBUG_SERVER: 1
      #LT_LOGGER_CALLER: 1
      #LT_LOGGER_TASK: 1
      LT_LOGGER_TIMESTAMP: 0
      LT_LOGGER_CALLER: 0
      LT_LOGGER_TASK: 0
      LT_LOG_HEAP: 1

logger:
  level: VERY_VERBOSE

During this time I rebooted my router twice and after each time I observed the following assertion, followed by a WDT reset:

The log is scrambled a bit, but it seems that mdns_netif_ext_status_callback() incorrectly handles some combinations of "reason" parameters which eventually causes calling mdns_resp_add_netif (lwip function) twice for the same netif, which triggers an assertion. Possible that it was broken by #263
