Why do you need to use a notebook where Linux works already for kgdb? That's traditionally only used to bring up new hardware platforms.
I just used a old notebook as target to learn how-to debug with kgdb. inspired by the debugging Chapter 4 in the LDD3 Book.
Also, there is USB serial debugging cables as there is a special mode in the USB 2 and 3 controllers that can be enabled to handle serial messages without interrupts for console/printk early messages that people use. The cables are not cheap to enable this, but worth it if you have to debug this type of target system.
can you point us to such a cable? Best Regards, Oliver
