great work!

I think that is the number of interrupt errors logged - if you cat 
/proc/interrupts on a desktop linux box you will see the same thing.

I think you'll find that the driver 
(linux/arch/microblaze/kernel/xmbserial.c) is creating two instances. 
There's a simple struct array initialiser at the top of that file that 
contains the details of each serial port - just remove the one you 
aren't using, and recompile.

John
