Setting up a serial console is not difficult, however it requires a 2nd system, as well as a serial cable (also known as a null modem cable).

Attach the serial cable to the serial ports of the two systems.

On your target system, add the following additional kernel parameters:
console=ttyS0,115200 console=tty0

On the 2nd system, you can use 'screen' to capture the serial output:
screen /dev/ttyS0 115200

Note that I referenced the first serial port, /dev/ttyS0, in my examples above. You can grep dmesg output for ttyS to see if your systems are using a different serial port.

If everything is setup correctly, you should see the boot time output in the serial c
onsole, and then you should also be able to capture any kernel messages that are generated when the system crashes.
