Don't forget to enable early printk support in Kconfig either. Another trick to get early printk output using JTAG: Look for the address of __log_buf in System.map, then use your debugger to dump that region in ASCII format. This is the printk buffer, so you can any printk output there, including the kernel crash dump.
