The kernel only allows 2k and 3k RSA keys in FIPS mode. Please check your RSA 
key used for signatures.

                /* In FIPS mode only allow key size 2K & 3K */
                if (n_sz != 256 && n_sz != 384) {
                        pr_err("RSA: key size not allowed in FIPS mode\n");
                        return -EINVAL;
                }

Ciao
Stephan
