Can you look back further in your kernel output, see if you can spot the bit
where it's trying to load the keys. Look for things from modsign_pubkey.c:
pr_notice("Loading module verification certificates\n");
...
pr_err("MODSIGN: Problem loading in-kernel X.509 certificate (%ld)\n",
PTR_ERR(key));
else
pr_notice("MODSIGN: Loaded cert '%s'\n",
key_ref_to_ptr(key)->description);

Hmmm... I suspect it's that. We need a hash to verify the key's own
signature too - and if you're using the key my autogen patch created for you,
I think that would be SHA1, so that must be built in too.
If you can see your kernel log (assuming a panic doesn't prevent you), I
suspect you'll see something like:
MODSIGN: Problem loading in-kernel X.509 certificate (-65)
which is -ENOPKG.
The answer would be to either select SHA1 in Kconfig or, if possible, to tell
openssl to use the same hash algorithm to sign the key as we're going to use
in signing the modules.
