In addition to what Steve has said, I'm wondering if you can work around this by using faketime when signing.

Kernels, upon kexec, check that message signature is within the validity of the X.509 signing certificate. When using original canonical kernel team test key, I no longer can kexec kernels, as the test key has expired. UEFI specifications in general ignore signing time. IMHO we should remove / not include signing timestamp in the UEFI signatures to avoid this. --- i guess openssl needs to provide ability to create signatures without signingtime attribute.
