I've seen this problem and I think it originates in the offloading of
digests through cryptodev. For this reason and also for performance, I
keep digest offloading disabled. Openssl issues a ton of calls to
digests for reasons not related to digests themselves (RNG ?).

What I would do is disable digest offloading in eng_cryptodev.c on your
Gentoo copy of Openssl and see if it satisfies your setup (make sure
Openssl is not built with USE_CRYPTODEV_DIGESTS).
