Hi,
  I don;t know if others have noticed less SILO overflows since 
I changes the interrupt system.
THis has not removed the problem completely. One thing people
can try and will probably be in future kernels is to
lower the serial FIFO trigger point from 8 to 4
(search arm32/mainbus/com.c for FIFO_8 and replace with FIFO_4)
This is significantly reduced my SILO overflows as it will give
more times between the serial interrupt and the FIFO actually
filling up.

CHeers,
