Enabling ZBOSS_OSIF_LOG_LEVEL_DBG breaks all Zigbee functionality

By default, CONFIG_ZBOSS_OSIF_LOG_LEVEL_CHOICE was set to ZBOSS_OSIF_LOG_LEVEL_INF.  But I'd like to increase the log level to debug a problem I'm seeing.  When I increase verbosity to ZBOSS_OSIF_LOG_LEVEL_DBG the device is no longer even able to join the network.  I suspect that blocking on UART prints is altering the timing so badly that ZBOSS is missing deadlines/packets/etc.

Is there a workaround for this?  Ideally a known-good set of options that lets me get ZBOSS_OSIF_LOG_LEVEL_DBG level output without breaking the Zigbee stack?
