Latency traces with timestamps might be quite useful, they'd probably also tell you why it happened. I can't reproduce it, nobody has provided numbers so even if I wanted to work on it I couldn't do much. Instead I have lots of real tty, ATA and other work that needs doing which has quantified data, is reproducable and needs doing, so that will get done.
