One thing to check is that "make oldconfig" can actually change the
configuration if things were moved behind a new top-level configuration
parameter or such. I'm not saying that's the case here, but it's possible
that things like the i2c changes might have made you inadvertedly changed
some config option.


I suspected so. However the acpi and i2c section of the two config are
identical. I report the only selected options:

Power management options (ACPI, APM)  --->
 [*] Power Management support
 [*]   Software Suspend (Hibernation)
 ACPI (Advanced Configuration and Power Interface) Support  --->
   [*] ACPI Support
   [*]   Sleep States
   <M>   Button
   <M>   Video
   <M>   Fan
   <M>   Processor
   <M>     Thermal Zone
   (0)   Disable ACPI for systems before Jan 1st this year

Device Drivers  --->
 I2C support  --->
   <M>   I2C device interface
   I2C Hardware Bus support  --->
     <M> VIA VT82C596/82C686/82xx and CX700

It's a regression, although I'd like to know more about your cases. It's
just hard to tell what happened: was it a i2c/hwmon driver that got
broken, or is it some sysfs file that got buggered, or what..

For example, "dmesg" output before and after (preferably as a diff between
the two), and what modules you had loaded in the working/nonworking case.



The first column of lsmod list the same modules in both kernels. The
diff-ed dmesg is attached.
