That's not an error.  To use the crash dump functionality, you have to
add an option to the kernel boot command line that reserves some RAM for
the crash kernel.  That message is just telling you that you didn't do
that so there can be no crash kernel loaded.

I don't speak for anybody but myself - that's enough trouble.
