what does this mean?

  during kernel booting ,I find a lot of interupt info writed into bochs' logfile.
  as below:

   
   03612529289i[CPU0 ] interrupt(): INTERRUPT TO SAME PRIVILEGE
   03612533288i[CPU0 ] interrupt(): IDT.limit = 0x7ff,address = 0x822be00
   03612533288i[CPU0 ] interrupt(): vector = 20, TYPE = 0, EXT = 1
   03612533288i[CPU0 ] interrupt(): INTERRUPT TO SAME PRIVILEGE
   03612537291i[CPU0 ] interrupt(): IDT.limit = 0x7ff,address = 0x822be00
   03612537291i[CPU0 ] interrupt(): vector = 20, TYPE = 0, EXT = 1
   03612537291i[CPU0 ] interrupt(): INTERRUPT TO SAME PRIVILEGE
   03612541290i[CPU0 ] interrupt(): IDT.limit = 0x7ff,address = 0x822be00
   03612541290i[CPU0 ] interrupt(): vector = 20, TYPE = 0, EXT = 1
   03612541290i[CPU0 ] interrupt(): INTERRUPT TO SAME PRIVILEGE

   .....
 
  Is this situation  normal  ? or something get wrong?

thanks!
