[REGRESSION] Kernel booted via kexec fails to resume from hibernation

Not confident, but maybe you can try latest mainline kernel see if the
below commit helps:
https://web.git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a2498e5c453b3d8d054d77751487cd593332f8c2

I noticed the e820 export is different for v4.9.337 and v5.4.291

Thanks
