    This is still BUG 71711
    https://bugzilla.kernel.org/show_bug.cgi?id=71711

    3.12.15 works very well
    3.13.7 fails
    3.14.0-rc8 fails

    I've tried the tmon tool, now, too. Nice eyecandy and for monitoring!

    I've tried to revert all "thermal" related patches from
    3.12.14->3.13.7 from 3.13.7. But they don't seem to matter. (Even
    if I apply the vice-versa patch to 3.12.15.)

    So "thermal" is out?

    For the failing kernels: Not any reached trip point (active)
    triggers ONE fan action!

    Next would be ACPI, to be investigated,

    THX for this audience,
    Manuel Krause
