Checked on my laptop http://paste.opensuse.org/view//92547497, the difference really is with the parameter spectre_v2=retpoline, but still this is not enough, a conflict of patches may have occurred somewhere, I saw a package with a bunch of patches somewhere, and a few were very old, 6 years ago were created, most likely they have not been needed for a long time, and now such patches can cause only problems
