Okay. less. My am335x-evm freezes after a while for no obvious reason.
The data that hits the RX fifo is still received but the TX won't do
anything. The DMA request is pending, the FIFO level is @64 bytes and
the UART doesn't make any progress.
On beagle-board I see what you described: less on a file and nothing
happens.
Disabling DMA seems to help fix the problem omap3. Nothing changes for
am335x.
