Did a bit of digging and found a Technical Note on Kernel Panics: https://developer.apple.com/library/content/technotes/tn2063/_index.html

I've skimmed over it and it looks good. The Isolating the Crash section will be of most help in this case, as well as: How to Read the Panic Log from an Intel-Based Mac as knowing how to read the log will help you debug it.
