Yeah; things get a bit unpredictable at times. I'll do some further
digging to try and understand why.
I still think it's a dodgy mix of issues with periodic calibration and
rate control.

I'm still working out the kinks with my current patch. I'll post
another one shortly for you (and others!) to try.

Finally, have you seen any device timeouts? Or odd traffic hangs?

Thanks,


Adrian
