Have you tried the "fast" flag for
the $_ports option? And does it load
your CPU to 100% ?

But this was only for the I/O that is
done via some filesystem device nodes
and for the socket I/O. So networking
performance is really improved, but
the port I/O is unaffected. Furthermore,
unless you use the "fast" port I/O,
it can be even slower now due to a
client-server approach.

Maybe it is due to some changes in
configuration, but this can be a bug
just as well.
Does your driver uses some particular
IRQ that you specify in $_irqpassing ?
Try producing a debug log, such as
-D9+T for ports I/O and -D9+r for IRQs
and maybe this will shed some light on
the problem. And then also you can see
in what 1.1.4.x pre-release the problem
started to happen.
