could you please test uart_v10_pre3? I dropped a few register sets and
delayed the register update until TX-DMA is complete. I am traveling
currently and have only my boneblack and it passes my limited testing.
If it solves your problems, too then I would address Heikki's latest
comments and prepare the final v10 (and I hope I didn't break beagle
board in between).
