Actually it was not. Some reports have cited problems back
to 6.0 or before.

The watchdog design was fundamentally flawed from an SMP
point of view and needed to be changed.

We also didnt want to go backwards if possible. My Intel driver
had support for new hardware that was good to pick up.

There's lots of new stuff coming too, so stay tuned :)
