My first thought is to try to connect via a serial port or similarly a USB based
port and get some sort of continuous stream of log data that I can capture on
another machine.

If you have a network, netconsole may be an option.  If you are using UEFI
boot, using pstore to save the panic message might work as well.

I also suppose that I could use SSH to login remotely and likewise grab logs.

If your kernel is in fact locking up, SSH will probably not be an option.


I managed to get a picture of the console.  I posted everything here:
