Hello, I am using a 3.10 kernel on a product. As soon as i get the shell prompt is displayed - The serial console freezes indicating an apparent hang and watchdog does a hardware reset.
I wanted to check if there is a way of debugging such an issue. I know that record saying "entering function" and "exiting function" somewhere in the memory which i could access after reset and then find out who cause the freeze. However, then i need to add such an instrumentation to the whole kernel. which is very time consuming and a real pain. Could anyone suggest a better way of debugging kernel freeze. Thanks and Regards, Ryan. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
