No, not at all. I booted with the old 2.6.15.7 kernel and in this case the
interrupt counter steadily increased. May it mean that something is wrong
with serial port? The port itself is working, I tried with an app reading
and writing data through the port (it does not use pin 1 howvever).

I attach the config file for both the new and old kernel, it may help.
