well when writing normall C code you can stop the program and hang it until
a debugger is attached but the kernel is harder because a debugger cannot be
attached
so when you have written code to try to test for things eg check for certin
conditions that
should not happen and they exist you can call BUG to get a kernel opps which
could have gone
unnoticed but could be much more fatel down the line like memory curruption
etc..
hope this helps a bit
