    i have just triggered this crash too. Please, when you know about bootup
    crashes in your code send a patch to the lkml thread so that people can
    apply it and have a working system.

    Note that the new crypto/prng.c driver has very bad quality:

    total: 45 errors, 21 warnings, 1 checks, 410 lines checked

    It has tons of completely unacceptable code mistakes in it.

    And the commit log says:

    | commit b8454eebe380677789735fd6bad368af2e6b2d1e
    | Author: Neil Horman <nhorman@tuxdriver.com>
    | AuthorDate: Mon Jul 7 22:41:31 2008 +0800

    | crypto: prng - Deterministic CPRNG

    i.e. this patch went in just 7 days from development to upstream, with
    insufficient review, with no linux-next presence at all (as of
    linux-next when v2.6.26 was released) and insufficient testing.

    That's not how it's supposed to be.
