Hi,

   good afternoon to all. I have a question that probably is just due to my
   ignorance, but I hope you will be nice with me...

   I am trying to debug S3 suspend, so I compiled the serial console in. I
   noticed a strange thing. If I boot with

           console=ttyS0,115200n8 console=tty0 

   I have *most* messages echoed to the serial line, but for example magic
   sysrq-t and sysrq-t simply put "SysRq : Show Memory" on both and the
   dumps goes just to tty0. 
   
   If, on the other hand, I boot with just 

           console=ttyS0,115200n8

   all messages goes to the serial console. Is this expected/normal
   behaviour? If yes, I think it should be added to
   Documentation/serial-console.txt...

   TIA, 
           Romano
