Drivers ought to be able to handle interrupts coming in at those
points; some don't and need to be caught.

Say Y here to make BUG() panics output the file name and line number
help
If you say Y here the resulting kernel image will include
debugging info resulting in a larger kernel image.
+ This adds debug symbols to the kernel and modules (gcc -g), and
+ is needed if you intend to use kernel crashdump or binary object
+ tools like crash, kgdb, LKCD, gdb, etc on the kernel.
Say Y here only if you plan to debug the kernel.
If unsure, say N.
