Wysocki" <rjw@...k.pl> Subject: Re: [REGRESSION] [2.6.37-rc1] Fan noise after suspend to ram/disk 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 On Sat, 2010-11-06 at 03:49 +0800, Maciej Rutecki wrote: > On piątek, 5 listopada 2010 o 01:27:34 Zhang Rui wrote: > > On Fri, 2010-11-05 at 00:06 +0800, Maciej Rutecki wrote: > > > 1. > > > Last known good kernel: 2.6.36 > > > Bad kernel: 2.6.37-rc1 > > > =============================== > > > > > > 2.
