All looks good when installing the three packages from wily-proposed:
linux-headers-4.2.0-36-generic linux-image-4.2.0-36-generic
linux-image-extra-4.2.0-36-generic. The kernel did not deference the
NULL pointer, and the particular OpenSSL self test passed:

    make test
    ../test/recipes/25-test_x509.t ............. ok
    ../test/recipes/30-test_afalg.t ............ ok
    ../test/recipes/30-test_engine.t ........... ok

And the only thing I see under dmesg:

    $ dmesg
    ...
    [ 913.294639] NET: Registered protocol family 38
    $

A small nit, which is probably due to my misunderstanding of the way
dependencies are handled when using Selective Upgrades
(http://wiki.ubuntu.com/Testing/EnableProposed#Selective_upgrading_from_-proposed).
When I performed only 'apt-get install
linux-image-4.2.0-36-generic/wily-proposed', the machine did not boot,
and it was stuck at the initramfs prompt. I needed to install
linux-image-extra-4.2.0-36-generic manually.
