I'd like to get some processor related settings from your machine to see
what's going on. Can you do the following:
sudo add-apt-repository ppa:colin-king/powermanagement
sudo apt-get update
sudo apt-get install intel-thermdump
sudo intel-thermdump > thermdump.log
and attach the thermd
Tested Timo's package and my eventstat tool is showing ~2-5 events/sec
on an idle machine - this is a most excellent result - a huge
improvement! Thanks! :-)
Note: With a webbrowser running with some stupid flash animation it
averages ~20 events/sec and glxgears its ~60 wakeups/sec, but that's to
Confirmed, a locked blank screen is generating 19-20 wakeups/second on
my idle machine.

Warning: "lpc_ich: Resource conflict(s) found affecting iTCO_wdt"
ACPI OpRegions are conflicting with the same I/O region used by the
lpc_ich driver for the Intel TCO (Total Cost of Ownership) timer
(iTCO_wdt, this is a watchdog timer that will reboot the machine after
its second expiration).

Warning: "lpc_ich: Resource conflict(s) found affecting gpio_ich"
This again is because ACPI OpRegions conflict with the same I/O region
used by the lpc_ich driver, this time for the GPIO region. Again, I

I don't think this are bugs per-se. The lpc_ich driver uses these I/O
regions that are already reserved by ACPI OpRegions and they seem to co-
exist OK without any issues. The warnings are alarming, but can be
ignored. There's nothing to fix.
