If you can hook a serial cable to your system and boot it with
console=/dev/ttyS0 console=tty0 (assuming you hook ttyS0, and adding
baud-rate as needed) you can grab possible kernel out this way.

Alternatively you can also use netconsole and capture output on
a second system on your network (e.g. with netcat).

See Documentation/kernel-parameters.txt and Kconfig help for
netconsole for details.
