A busy preempt_rt system can easily delay background work like uart for a LONG time. > # Something like > tty_driver->low_latency = 1; Unfortunately that doesn't do anything at all. There are patches floating around that convert the tty stuff into a proper kthread that can be given sched_fifo priority. You'll have to port those or do something similar yourself. Recently there has been some talk on LKML on just this topic, namely getting "low_latency" to actually do something again. But I wouldn't hold your breath.
