    I gave this a go on 151012 (014 isn't available as an AMI yet, and I
    can't get the 006 AMI to accept a ssh key pair on instance creation),
    and saw the same thing.  powertop appears to segfault in
    string_to_decimal / libc.so.1.

    I then tried rebuilding powertop from the OmniTI illumos-gate build
    scripts, but found that omnios-build:build/illumos/build.sh is a
    little fussy for the uninitiated.

    This sounds like a libc or kernel change, but I can't imagine why it
    would show up on both 012 and 014.  Maybe someone with a working build
    environment can dig further?
