           Summary: ASUS Bios not detecting SMBus PCI Device
    Kernel Version: 2.6.16 - Debian testing source
            Status: NEW
          Severity: low
             Owner: khali at linux-fr.org
         Submitter: conrad.williams at centralinfo.biz


Most recent kernel where this bug did not occur: NA

Distribution: Debian Sarge 3.1 - running Deb Testing Kernel 2.6.15 compliled
from deb.source.
The changelogs in the kernel do not reference any further changes in this area
since this kernel release.

Hardware Environment:
Mobo  ASUS PU-DLS  (S for SCSI, should also apply to PU-DL) latest Bios 1008
Xeon 2.4 512M, running PCI-X.
Has SMBus connector for other devices, which is "obvously" on the I2C bus.
Main chip is an Intel E7501 (Plumas 533) MCH which I believe is the adapter;
Intel 82801CA/CAM (ICH3).

Software Environment:
sensors version 2.10.0 with libsensors version 2.10.0
I2C is compiled in as a module, in the kernel .config file, as per the 2.6
settings at lmsensors site.

Problem Description:

In a nutshell, need to turn on the SMBus PCI device for an ASUS mobo. How to
hack quirks.c and where to start for a beginner.

There was reference to this mobo, back in May 03, with the following thread;
http://lists.lm-sensors.org/pipermail/lm-sensors/2003-May/002471.html
and then again in Aug 03
http://lists.lm-sensors.org/pipermail/lm-sensors/2003-August/004177.html

Have done sensors-detect, and found only the i2c-isa bus driver, and pc87360
driver, which is not returning any sensor information. I'm prepared to get this
working, but I don't know where to start. I have as much information as I can at
this stage to get things started, and am prepared for the long haul. 

I have read the README.p4b, and about  driver `i2c-i801.o' and the 2.6 kernel
calling the quirks.c code. I have looked at the quirks code, and not found
anything relating specifically to this system or chip in this code.

 Now follows a summary of the probes I have just done.
 Just press ENTER to continue:
Driver `pc87360' (should be inserted):
  Detects correctly:
  * ISA bus address 0xecc0 (Busdriver `i2c-isa')
    Chip `Nat. Semi. PC87360 Super IO Fan Sensors' (confidence: 9)


I will now generate the commands needed to load the I2C modules.

To make the sensors modules behave correctly, add these lines to
/etc/modules:

#----cut here----
# I2C adapter drivers
i2c-isa
# I2C chip drivers
pc87360
#----cut here----

Output from sensors;

pc87360-isa-ecc0
Adapter: ISA adapter

In the log/messages file; following may be of note;
PCI quirk: region e400-e47f claimed by ICH4 ACPI/GPIO/TCO
PCI quirk: region ec00-ec3f claimed by ICH4 GPIO
PCI: Ignoring BAR0-3 of IDE controller 0000:00:1f.1
PCI: Transparent bridge - 0000:00:1e.0
PCI: If a device doesn't work, try "pci=routeirq".  If it helps, post a report
## What does the above mean, does it relate to hidden PCI device?

Steps to reproduce:
Follow the standard lm-sensors install directions.
