Hello Louis,

I don't think the message itself is bad, the situation for users has
a problem, I guess.
If a distribution provides a combination of a kernel and a makedumpfile
which doesn't support it, it stands to reason that users send a bug report.

I suspect such message doesn't make sense because even the latest makedumpfile
doesn't support the kernel version in your most cases, right ?

I know I have to work harder for following up the latest kernel ASAP,
but I don't agree with your suggestion.
