When I communicate at second uart with high speed (460800 and 921600) between two kinetis K10 I see RX-IRQ stopped after some time-lapse.  On other speeds all works well.

1) I'm using the kuart MQX driver (3.8) in interrupt mode and I configured it for this speed.

2) I'm using a 40MHz crystal and 40MHz  sys bus.

 

What is this might be?

 

Thanks a lot.
