What I've seen few times is typing a key on the serial console echoing back the previous character typed while the new character won't get displayed until hitting keyboard again. Only rebooting the device seems to solve this. This is with 4430 ES2.3 revision. I wonder if we're missing some parts of errata i202 handling in omap_8250_mdr1_errataset()? Also, I'm seeing an issue where the UARTs won't idle on init with 8250_omap driver if connected to the wl12xx bluetooth port unless I write some data to the port first. It does not seem to be related to the rts/cts lines being wired as I've tested muxing them out of the way.
