i.e. enable the following Kconfig options:

CONFIG_DEBUG_LL=y
CONFIG_EARLY_PRINTK=y
CONFIG_TEGRA_DEBUG_UART_XXX=y

(where XXX above is the serial port you're using; look in menuconfig)

and add "earlyprintk" to the kernel command-line. That should hopefully
show the cause of the crash/hang.

BTW, what is your kernel command-line?
