That's what I was afraid of.  This might be rather a problem in user-space
side, e.g. dracut.

To be sure, could you try the following?

- Download kernel-default-5.14.21-150500.3.1.gad9a743.x86_64.rpm from my OBS
repo

- Install it on the Leap 15.4 system directly via zypper install:
  zypper in kernel-default-5.14.21-150500.3.1.gad9a743.x86_64.rpm

- Retest hibernation.

I guess this may work.  Once after testing, you can remove the kernel again:
  zypper rm kernel-default-5.14.21-150500.3.1.gad9a743


Once after the test, you can uninstall the test kernel package again via zypper
remove (with the exact kernel version).
