We found that the db in Acer machine has self signed certificates (CN=DisablePW or CN=ABO) that they used obsolete OID 1.3.14.3.2.29 sha1WithRSASignature and 2.5.29.1 subjectKeyIdentifier. Kernel emits -65 error code when loading those certificates to platform keyring: [ 1.484388] integrity: Loading X.509 certificate: UEFI:MokListRT [ 1.485557] integrity: Problem loading X.509 certificate -65 [ 1.486100] Error adding keys to platform keyring UEFI:MokListRT Because the -65 error code is not enough for appeasing user when loading a outdated certificate. This patch add messages against 1.3.14.3.2.29 and 2.5.29.1 OIDs.
