Here's some things I ran into. - Basic console use is better than the previous series. It behaves pretty much like the omap-serial implementation. - ncurses based applications (vi, less) don't play nice for me on the console with this series. less doesn't show me anything. vi doesn't return to console properly. - I seem seem to get stuck in a "serial8250: too much work for irq%d" loop somewhat reliably. We have a rather demanding application with typically somewhere between 600 and 1000 byte packets being sent at 240Hz (roughly somewhere between 1.5 and 2 Mb/s). We run at baudrate 3500k. I get into this "too much work" thing already when running at 300 bytes per packet. I hope this is of some use to you. I'll do more testing later.
