Do you have this in cmdline?

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

You boot with something like this:


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.
