Yes, but you'll need to define the dump device and place to save the 
dump from the swap in the next reboot. In addition

makeoptions DEBUG=-g is needed in the kernel config as well (symbols!) 
options DDB_UNATTENDED can be a good idea.

I think that separate kernel and userland is a bad idea, especially now, 
when you have 5.3_STABLE kernel, and 5.3_RELENG userland. There are 
small and subtle changes in both which make the correct userland/kernel 
combination vital and following the correct procedure of 
compiling/installing them.
