on the other hand a kernel oops and system hang will always get noted. Rather
than a WARN() which simply sits in the log buffer. Remember that not all
users will be looking at console. If there's a kernel hang, we get a
core dump which is saved in the mtdoops (if you're using it) and can
send later to some central server for analysis.
