I've had some issues with the crypto engine conversion lately myself
also, but I think it happened only once enabling the crypto tests from
Kconfig. Anyway, the series I just posted contains fixes for the crypto
engine registration, give it a try and see if it helps (or patch #10/11
in that series at least.)

Hi,
I’ve been working with a Beaglebone Black rev. C lately. Distro
is Fedora 24. Things run smoothly with the original 4.5 kernel,
but not with the 4.6 one that comes with a ``dnf update``: The
system does not reboot or poweroff normally and there’s an oops
with every run:

I’ve bisected the issue down to this change:
0529900a01cb840feb7f7e2f64ed88f7a9ed0031 is the first bad commit
commit 0529900a01cb840feb7f7e2f64ed88f7a9ed0031

crypto: omap-aes - Support crypto engine framework
Integrate with the newly added crypto engine to make the crypto hardware
engine underutilized as each block needs to be processed before the crypto
hardware can start working on the next block.
Which adds the “CRYPTO_ENGINE” module. After blacklisting the
module “omap_aes” the issue vanishes (no oops, system reboots).
Please let me know if you need more information or want me to run
further tests.
