Do you have this in cmdline?

        resume=         [SWSUSP]
                        Specify the partition device for software suspend
                        Format:
                        {/dev/<dev> | PARTUUID=<uuid> | <int>:<int> | <hex>}

You boot with something like this:

crashkernel=512M-2G:128M,2G-64G:256M,64G-:512M

Check dmesg to see whether it managed to reserve memory. Then you do:

# kexec --noefi -l bzImage --initrd=initrd.img --reuse-cmdline

# kexec -e

That last one loads it.

Anyway, something like that. I have this in my notes saying it worked at
some point.
