The patch titled
smbus unhiding kills thermal management
has been added to the -mm tree. Its filename is
smbus-unhiding-kills-thermal-management.patch
See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
From: Pavel Machek <pavel@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.
