Looks like the machine's SecureBoot setup isn't able to verify the module, and thus is preventing it from being loaded. Easy "sanity check" would be to (temporarily) disable that if possible, and try loading the module again. At the very least, you'll be able to prove the module itself isn't broken. If that works, then either a. You missed a compile-time switch to sign the module OR b. You missed a post-compile "sign" step OR c. SecureBoot cannot validate the signature (e.g. your key isn't loaded into its trust-store, you signed with the wrong key, etc.) It's not much to go on, but hopefully it helps ... -- |_|O|_| |_|_|O| Github: https://github.com/dpurgert |O|O|O| PGP: DDAB 23FB 19FA 7D85 1CC1 E067 6D65 70E5 4CE7 2860
