Hrm, my kernel merely changed the suspend/resume functions and nothing else, so the behavior change except for suspend/resume isn't expected. And, it doesn't change the binding, so the blacklist is still necessary. It was asked only for testing the suspend/resume problem. You should install only kernel-default.rpm, nothing else. At easiest, download kernel-default-5.15*.rpm from the URL and install it manually via zypper install.
