There is a patch named "ARM: edma: unconditionally ack the error interrupt". I have the feeling that this is not really required once we delay set_termios. I couldn't reproduce the bug with beagleblack with my usual test case. For your "too much work for irq" problem: Could you add trace_printk() in tx/rx dma start/complete, and irq routine? The interresting part is what is the irq routine doing once entered. It might be a condition that is ignored at first and "acked" later while serving another event. Or it is really doing something and this is more or less "legal". >Thanks, >Frans Sebastian -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
