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?
