Subject: Re: [REGRESSION] [2.6.37-rc1] Fan noise after suspend to ram/disk
Date: Mon, 08 Nov 2010 14:58:52 +0800 [thread overview]
Message-ID: <1289199532.8148.57.camel@rui> (raw)
In-Reply-To: <201011052049.55500.maciej.rutecki@gmail.com>
IMO, the only one that may cause this regression is commit
c57b62f5b1e6dd69ff8c96f6db7f86ea31c0e21f
some app may enable polling via procfs and update the thermal zone
status.
could you please attach the output of "grep . /proc/acpi/thermal/*/*" in
2.6.36 kernel?
thanks,
rui
