   > IF there is a call to syslog... If not, IRQs continue to write to intbuffer, until overflow. There is no guarantee on if and when the buffer will be flushed. At least from the IRQ's perspective.
   
   Oh, I forget this case. one solution(again) is work queue if it exist.

   This patch is important to recovery the log after reboot:
   https://github.com/apache/incubator-nuttx/pull/3808
   Please remeber to put the ram buffer out side .bss section, otherwise the initializition code will zero it before we have a chance to restore the last log.
