Yes, I use "options > PRINTF_BUFR_SIZE=128". And I don't know if that's related to the > patch. No, it's not related, it's a probabilistic thing. Those "Launched!" messages are printed from threads running on freshly started APs and thus are executed truly parallel to BSP. BTW, is the above snippet from /var/log/messages or from actual console (e.g. ttyv0)? If it's from message, then could you please check how it looks on the console? -- Andriy Gapon
