Do you know an old sio driver is hardly usable?

There are many silo overflows, working with a terminal device is a
nightmare. There was a report about one crash with a message about a
spinlock holed more than 5 seconds (there is no core dump because it has
not repeated).

After a discussion in a Russian FIDO group I've change it on uart and
the problems gone.

I think a default driver should be changed from sio to uart until it
will be fixed.
