I applied this patch to the source of revision 4c5188bbeb88 : https://reviews.freebsd.org/file/data/46vn3u4fppozrmbpumm3/PHID-FILE-fpq3ig3mungpijncdlfe/D40481.diff
I've had no kernel panics using VSCode with this patched kernel.
This panic occurred frequently when the kernel was not patched, so this feels like an improvement.
