Just verfied that hwmon is new in kernel 2.6.14. But as I said, it works in my case.

Regarding your .config file, I can only say that my file was looking similar about half a year ago - and something didn't work...
What other I2C stuff is automatically loaded in your system?

What is your output if you do:

Code: Select all

modprobe i2c-core
modprobe i2c-isa
modprobe it87
dmesg | grep it87
I'm getting
it87: Found IT8712F chip at 0x290, revision 7
it87-isa 9191-0290: Detected broken BIOS defaults, disabling PWM interface
Don't know about the error message, never saw that before. But that shouldn't be our concern right now.

Okay here the related modules

Well, this is bad news. At least we know now that the it87 driver isn't working - but why???

Code: Select all

i2c_core               19288  13 it87,i2c_isa,i2c_nforce2,eeprom,tuner,saa7134,b2c2_flexcop,mt352,bcm3510,stv0299,nxt2002,stv0297,mt312
Jesus Christ, what is all this? Is all the stuff right of i2c_isa related to the TV-card?

saa7134 is my analog-tv-card and "b2c2_flexcop,mt352,bcm3510,stv0299,nxt2002,stv0297,mt312" my DVB-T-receiver.

I also tried to unload all of these drivers and reloaded i2c-stuff.

Can you get rid of i2c_nforce2 and eeprom completely?

tuner is probably related to TV, too. No?

I think it would be best to boot a system with the neccessary modules only. My feeling is that some of the i2c stuff is interfering or doesn't get initialized correctly or doesn't recover if used in a different way before. You know, I was also dealing with all this nforce2 and eeprom stuff at that time and it didn't work. But as I said, I tried so much that I can't tell anymore what finally did the trick. Right now I think it would be the best idea to recompile the kernel with the required modules only and to stay away from sensors-detect. Just modprobe the modules you need (see above) and see if the it87 driver finds the chip.

I think at this point there are few possible causes for the problem:
1. There is some interference within the i2c stuff (my favourite guess, since that that explains my problems from June/July, too)
2. There is some interference with your TV cards/drivers
3. You don't have a supported it87 chip or it is defect (unlikely, but BTW, how old is your mainboard? Did you buy it recently?)
4. The configuration is messed up somehow

Anyway, fact is that the it87 driver can't find the chip although we assume the chip is there.

I found the following in sensors.conf. Although this is not related to our case, this seems to be the kind of problem we are dealing with
# The following is for the Inside Technologies 786LCD which uses either a
# IT8705F or a SIS950 for monitoring with the SIS630.
# You will need to load the it87 module as follows to select the correct
# temperature sensor type.
# modprobe it87 temp_type=0x31
# The sensors-detect program reports lm78 and a sis5595 and lists the it87 as
# a misdetect. Don't do the modprobe for the lm78 or sis5595 as suggested.
This looks kind of familar to me. Back in June I had a some of these "found xxx sensor with thisandthat probability" when I ran sensors-detect. But it didn't find the it87 then.
One of the actions I did at that time (beside others) was to remove more and more sensors from the .config and to recopile the kernel. However, at that time I didn't know exactly what to exclude and if that makes a difference at all. So my way was kind of erratic.

Anyway, my experience and experiemces from others as well as the example from above make it quite clear that probing these sensors may be quite tricky. In your case there is the additional problem of the TV cards. Life would probably be easier without them since you could just take a running configuration and use it.

BTW, when talking about TV cards, did you set up your system as a 64-bit system (AMD64) or as a 32-bit system (X86)?

I set it up as x86_64 (64-bit), I wanted to use all "features" of the kernel.

"it87: Unknown parameter `temp_type"

OK, no difference here.

You probably tried that already, but what happens if you rmmod all i2c related modules, freshly load modules i2c_core, i2c_isa and it87 but don't load the modules needed for the TV cards any more. Would "dmesg | grep it87" give any result then?

You are right, I already tested it. No chance. My Bios shows the actual temperatures, there should be a sensor on the board, but I have also a special version of the A8N-E, but I could not find anything about a leck of this feature.
Okay, I hope you wouldn't kill me but do you have Windows installed on the PC? I tried it yesterday with mbm5 and did not have success either.

No, I definitely don't have an intent to kill anybody :wink:
But sorry, I never installed windows on that system. I'm using a different computer for the Windows stuff I need to do. The A8N-E is in a system that I use as a development system for a huge Java application. You know, it's rather configured like a server plus KDE and all the development stuff, very few other programs are installed.

However, a couple of months ago I checked the Asus BIOS update site. If I recall correctly you need some kind of special Windows driver if you use a BIOS newer than 1008 or something like that. Did you downgrade your BIOS accordingly before you tried to install Win XP?

Sorry, What is mbm5?

From asus.com:
A8N-E Bios version 1006
Please do read the description before updating BIOS
To avoid crashing file system, please do update the chipset driver to below version prior to this Bios.
For WinXP 32bit system, please download and update chipset drivers V6.65 or later
For WinXP 64bit system, please download and update chipset drivers V6.65 or later
For Win2k/2003 32bit system, please download and update chipset drivers V6.66 or later
For Win2003 64bit system, please download and update chipset drivers V6.66 or later
So I guess you even need to downgrade your BIOS to a version below 1006.

I need to modify my remark that I never installed Windows on that machine somehow. My first CPU was faulty and went down within a few minutes. In the process of figuring out what is going on there, I wanted to see if my problems may have to do with Gentoo's lengthy compilations (heating up the CPU). So I tried to install Windows XP. The installation went quite far but ultimately the CPU went down again before it finished. Up to that point I didn't have the feeling that Win XP had problems with the board. If I remember correctly, I had BIOS version 1001 on the board at that time.

Oh, you probably talk about the Mainboard Monitor

I also could update the NForce-drivers. Repairing my XP-Version was quite simple, Preesing "F8" at boot-time and I choosed the option that I would run the last known running configuration, don't know how it's called correctly in the english version of XP.

OK, so you had Win XP installed already and then you ran into problems after the BIOS upgrade.

No I ran into problems when my program told me "No SMBus driver found" and I installed one...
