[lm-sensors] Problems with i2c_i801

[lm-sensors] Problems with i2c_i801

[James Davis]

I was about to post a support ticket but saw that I ought to post here
instead whilst the system is down. 

I'm running Debian/Etch with a 2.6.15-1-686 kernel. The I think the
system is a Dell Optiplex GX280 which from reading Dell's website gives
me an Intel 915G chipset (if I've correctly identified the system!).
Running sensors detect gave me the following to add to my modules.conf.

#----cut here----
# I2C adapter drivers
i2c-i801
# I2C chip drivers
eeprom
#----cut here----

I've loaded these modules Looking through the output of lsmod I get:

cressida:/home/james# lsmod | grep i2c
i2c_dev                 8640  0
i2c_i801                7916  0
i2c_core               19280  3 eeprom,i2c_dev,i2c_i801

sysfs appears to be correctly mounted:

cressida:/home/james# mount | grep sys
sysfs on /sys type sysfs (rw)

But when I run sensors I get the following output:

cressida:/home/james# sensors
Can't access procfs/sysfs file
Unable to find i2c bus information;
For 2.6 kernels, make sure you have mounted sysfs and libsensors
was compiled with sysfs support!
For older kernels, make sure you have done 'modprobe i2c-proc'!
cressida:/home/james#

Any idea what I'm doing wrong? :(

Many thanks,

James

Where do the "sensors" program come from? Debian package?
Hand-compiled? Which version ("sensors -v")?

Note that no hardware monitoring chip was detected on your system, so
if that's what you are after, fixing the problem above won't help you
much. Either your system has no hardware monitoring chip, or
sensors-detect failed to detect it for some reason. The complete output
of "sensors-detect" may let us help you in the second case.

The Debian package

cressida:/home/james# sensors -v
sensors version 2.10.0 with libsensors version 2.10.0

This program will help you determine which I2C/SMBus modules you need to
load to use lm_sensors most effectively. You need to have i2c and
lm_sensors installed before running this program.
Also, you need to be `root', or at least have access to the /dev/i2c-*
files, for most things.
If you have patched your kernel and have some drivers built in, you can
safely answer NO if asked to load some modules. In this case, things may
seem a bit confusing, but they will still work.

It is generally safe and recommended to accept the default answers to
all
questions, unless you know what you're doing.

 We can start with probing for (PCI) I2C or SMBus adapters.
 You do not need any special privileges for this.
 Do you want to probe now? (YES/no):
Probing for PCI bus adapters...
Use driver `i2c-i801' for device 00:1f.3: Intel 82801FB ICH6
Probe succesfully concluded.

We will now try to load each adapter module in turn.
Module `i2c-i801' already loaded.
If you have undetectable or unsupported adapters, you can have them
scanned by manually loading the modules before running this script.

 To continue, we need module `i2c-dev' to be loaded.
 If it is built-in into your kernel, you can safely skip this.
i2c-dev is already loaded.

 We are now going to do the adapter probings. Some adapters may hang
halfway
 through; we can't really help that. Also, some chips will be double
detected;
 we choose the one with the highest confidence value in that case.
 If you found that the adapter hung after probing a certain address, you
can
 specify that address to remain unprobed. That often
 includes address 0x69 (clock chip).

Next adapter: SMBus I801 adapter at e8a0
Do you want to scan it? (YES/no/selectively):
Client found at address 0x08
Client found at address 0x30
Client found at address 0x32
Client found at address 0x44
Probing for `Maxim MAX6633/MAX6634/MAX6635'... Failed!
Client at address 0x50 can not be probed - unload all client drivers
first!
Client at address 0x52 can not be probed - unload all client drivers
first!
Client found at address 0x69

Some chips are also accessible through the ISA bus. ISA probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.

Do you want to scan the ISA bus? (YES/no):

Some Super I/O chips may also contain sensors. Super I/O probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.

 Sorry, no chips were detected.
 Either your sensors are not supported, or they are
 connected to an I2C bus adapter that we do not support.
 See doc/FAQ, doc/lm_sensors-FAQ.html, or
 http://www2.lm-sensors.nu/~lm78/cvs/lm_sensors2/doc/lm_sensors-FAQ.html
 (FAQ #4.24.3) for further information.
 If you find out what chips are on your board, see
 http://secure.netroedge.com/~lm78/newdrivers.html for driver status.


:-( doesn't look hopeful.

OK. Can you make sure that libsensors was compiled with sysfs support?
"ldd /usr/lib/libsensors.so" should have one line for libsysfs.

No I2C/SMBus hardware monitoring chip...

You have a Super-I/O chip (a.k.a. LPC chip) we don't know about. Given
the output above, this could be a chip made by ITE, National
Semiconductor or SMSC. Can you find some documentation about your board
and/or open the case and locate that chip? Typically they are
rectangular, with 128 pins, and measure about 20 mm by 12 mm. Sometimes
these chips have hardware monitoring functionalities.

Does the BIOS of your system display any hardware monitoring
information? Is this system somehow advertise as having hardware
monitoring capabilities?

I found the following SMSC chip:

LPC47M584-NC
B0443-AL1314
8H1190280

Here's a link to a photograph.

Nothing there, I guess that doesn't bode well..

Looks like we had a report for that chip already:
http://netroedge.com/~lm78/readticket.cgi?ticket\x1998

Dell system too... SMSC doesn't have anything about that chip on their
site. I guess this is a custom chip they made for Dell.

Indeed. I've gone as far as I could, but now, without any information
on that SMSC chip, there's nothing left I can do. Unless you can get
information from either Dell or SMSC, this is the end of the road,
sorry.

Thanks for your help, I've written to SMSC but I'm not holding out on a
reply.

Thanks once again,
