Where can we get a powertop-2.1? I searched google and found
git clone git://git.kernel.org/pub/scm/status/powertop/powertop.git
is null now.

Really weird, my commit only change the lpc_ich.c which affects the TCO_WDT
driver. but from your .config file, neither CONFIG_LPC_ICH nor the
CONFIG_ITCO_WDT is enabled, which means the commit should not affect
your kernel, could you double check the .config file?
Thanks,
Feng
