The patch titled
smbus unhiding kills thermal management
has been removed from the -mm tree. Its filename is
smbus-unhiding-kills-thermal-management.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.
From: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@xxxxxxx>
Do not enable the SMBus device on Asus boards if suspend is used. We do
not reenable the device on resume, leading to all sorts of undesirable
effects, the worst being a total fan failure after resume on Samsung P35
laptop.
