Is this a regression?  Did 2.6.37 have the same problem?

Thanks.

this is got from the FADT table of your laptop"
           Control Method Power Button (V1) : 1
           Control Method Sleep Button (V1) : 1
this means that there is control method power button, and power button events are routed via GPE rather than fixed ACPI event, thus we do not register an handler for the fixed power button event(0x00000002).

(20110112/evevent-272)
this error message means that there is an power button fixed event generated, although the power button interrupt should be GPE.
Q1. does this message show up when you press the power button?
Q2. does the power button work well on your laptop? e.g. is there an menu pop up asking you to shutdown/restart/suspend/hibernate your machine, when you press the power button?

Question for me:
should we always register the fixed power button/sleep button event handler even if there is control method power button/sleep button?

bug closed as there is no response from the bug reporter.
please feel free to reopen it if the problem still exists in the latest upstream kernel.
