silo overflow == fifo overrun.  The former phrase is used in other
drivers, and I guess the change was made for the sake of consistency.
I imagine the rate has dropped considerably, though.  It may be a little
difficult to determine just how bad things were with the old driver, due
to bugs in the reporting mechanism, so don't try to measure this based on
your logs. :-)
