The warning in the subject, printed when the latest TW kernel update is installed by zypper, is caused by a bug in suse-module-tools. In the worst case, depending on which other packages are installed/updated in the zypper run, an initrd for the new kernel may not be created, causing *boot failure* after rebooting. Workaround: run dracut -f /boot/initrd-5.13.12-2-default 5.13.12-2-default manually after the update (likewise for other kernel flavors). If the boot failure has already happened, you'll need to boot a previous kernel or a snapshot and repair the initrd. The problem is fixed in suse-module-tools-16.0.9 from Base:System.
