I'm testing with 2.6.39 and our serial driver that's unique to our ARM platform. I suspect we have a problem with our serial driver but wanted to see if anyone has seen any similar behavior. When running with 2 serial ports, any input from a serial terminal running at the wrong baud rate (9600 instead of 115.2K) on a 2nd shell (not the console shell) causes the kernel to lock up. It doesn't crash, I'm still trying to understand what it's doing. I can no longer ping the board as the network was working prior. I just wanted to make sure there's not any known tty issues related to this.
