Lately my team has been seeing odd serial port hangs which seems to be coming from the linux serial driver(16550). I figured I ask the question just in case anyone has seen it before. Basically a simple test program which just prints characters in an infinite loop ends up hanging after about 4096 characters, the serial buffer size, if we increase the buffersize, we the hangup occurs there, so it is definitely related, the weird part is that if we press cntrl-c it starts to work again and prints out another 4096 characters or so. Any ideas?
