Package: lm-sensors
Version: 1:3.1.1-4
Severity: normal

Hi, 

since the 2010-01-30, "sensors" fails to read my sensors.

	No sensors found!
	Make sure you loaded all the kernel drivers you need.
	Try sensors-detect to find out which these are.

I haven't changed anything related to my modules or the sensors program
itself, but it fails for a reason I can't find.

sensors-detect points me to i2c-i810 and smsc47m192, which are both loaded:

i2c_i801                7766  0
i2c_core               15584  2 i2c_i801,smsc47m192

I also tried with the Sid version and the same happens.

>From the kernel log, I get things like that, which I don't fully get.

[ 3659.067814] smsc47m1: Found SMSC LPC47M15x/LPC47M192/LPC47M997
[ 3659.067910] ACPI: I/O resource smsc47m1 [0x680-0x6ff] conflicts with ACPI
region RTIO [0x680-0x6ff]
[ 3659.067971] ACPI: If an ACPI driver is available for this device, you
should use it instead of the native driver

Don't hesitate to ask for details. I also noted that it might be a duplicate
of #524038 (same module) or  #566184 (It also fails to set the defaults,
obviously).

Best regards, 

OdyX

Added in r8136, with the fixes from Steve and Adam.  Thanks.
