Ok, on a different machine, I was able to catch it over the serial console this time. This time I was able to get the Call Trace as well.
Below I'll give both the raw output, as well as running it through ksymoops.
(Again, if I'm doing something wrong, if I need to be giving more information, or if I need to provide something else of relevance, please let me know, I'll be more than happy to comply.)
The raw output.
Unable to handle kernel NULL pointer dereference at virtual address 00000080
