This is interesting. sensors is looking for another directory below /sys/class/hwmon/ which you don't have for reasons unknown:
| Code: | gentest ~ # ls -l /sys/class/hwmon/
total 0
drwxr-xr-x 2 root root 0 15. Jun 22:35 hwmon0
|
Inside that directory, I have a symlink "device" which points to the actual device:
| Code: | gentest ~ # ls -l /sys/class/hwmon/hwmon0/
total 0
lrwxrwxrwx 1 root root 0 15. Jun 21:02 device -> ../../../devices/platform/i2c-9191/9191-0290
--w------- 1 root root 4096 15. Jun 22:35 uevent
|
I suppose your /sys/devices/platform/i2c-9191/ looks something like this?
| Code: | drwxr-xr-x 3 root root 0 15. Jun 21:02 9191-0290
lrwxrwxrwx 1 root root 0 15. Jun 22:34 i2c-adapter:i2c-9191 -> ../../../class/i2c-adapter/i2c-9191
-r--r--r-- 1 root root 4096 15. Jun 21:02 name
drwxr-xr-x 2 root root 0 13. Jun 23:32 power
--w------- 1 root root 4096 15. Jun 22:34 uevent
|
If so, we have to find the "missing link", so to speak, which would be the "hwmon0" directory. I have no idea yet what creates it. |

After more research, digging through mailinglist archives, googling and trying to reproduce this, I'm almost out of ideas.
I would now suggest using the lm_sensors support flow-chart/diagnose web page. Follow it to the letter and feel free to record and post the flow of items you're going through.
Maybe that'll give us a new idea. |

For 2.6 kernels, make sure you have mounted sysfs and libsensors

For older kernels, make sure you have done 'modprobe i2c-proc'!

I am currently using the following kernel: 2.6.16-gentoo-r9
I have tried various things in tems of hardware monitoring support kernel modules, and I know my i2c settings are right (built in i2c-core, i2c-dev, and i2c bit banged, module eeprom and i2c-801, since this is a DELL gx620 with intel chipset).

The lm_sensors site has nothing on this that I can find, and google seems to only return the following answer: Load i2c-dev, yet, I have that built in so loading it is not an option.
Any help would be greatly appreciated.
Also of note, since it is complaining about missing sysfs (which is not it my fstab but is mounted), along with trying to start it from init.d, lsmod afterwards, etc...
I hope that somehwere is all this info is a clue to help me solve this....

Sorry, I have not fould a solution that works. If I get some time I may try downgrading the kernel to 2.6.15 and see if that helps.

Hey Raziel,
Did you get this Dell GX620 sensors to work? I'm having the exact same problem as you, with this Dell GX620...
I read in the http://www.lm-sensors.org/wiki/FAQ/Chapter3#SensorssaysCantaccessprocfssysfsfile that it's need to | Code: | | modprobe i2c_sensor |
but there is no i2c_sensor module:
| Code: |
2ks linux # modprobe i2c_sensor
FATAL: Module i2c_sensor not found.
|
Did you get any luck with it?

I believe this is only for 2.4 kernels so the docs are way out of date...

I gave up for now, haven't had time to really play with it, since this is my work box, and I haven't felt like staying late to debug, lol.

I think I just figured this out for those of us who only have/use i2c_i801 and eeprom (others who've had similar issues but with other chipsets and busses, the following probably doesn't apply to).
So, in 2.10.0, lm_sensor's sensors command doesn't consider chipsets that don't have actual sensor-like capabilities as sensors (this makes sense). So, lm_sensors start script will always fail when the sensors -s command is launched, and sensors command itself will always fail, with it's annoying "load sysfs" error 'cause there simply are no sensors with sensing capabilities.
if eeprom is loaded and otherwise seemingly working, you can run 'decode-dimms.pl', which is installed in the lm_sensors package 2.10.0 (maybe earlier versions, too, don't know offhand), and you will notice that it does output valid data.
Annoyed, but no longer stumped.

Wow... Thank you! That really was annoying me. Now I'm still annoyed, like you, but knowing why takes the edge off it.

I have similar problem on a HP NC8000 laptop.

I tried with a kubuntu livecd, the device it should be:

Kernel:

I suspect that the kernel does not recognize the device.
Any advice? |

Hi, about HP nc8000, I managed to get SMbus to appear.. by using *vanilla-sources* , not gentoo-sources.. as soon as I switch back to gentoo-sources, it disappears
now I can execute sensors.. and get PC health data out of it  |

Hi,
I am in a similar situation. AMD64x2, 939Dual-VSTA, gentoo-sources-2.6.17-r8, all lm_sensors and hw monitoring compiled as modules. sensors-detect works to load these modules:
| Code: | MODULE_0=i2c-ali1563
MODULE_1=i2c-isa
MODULE_2=eeprom
MODULE_3=w83627ehf
|
sensors -s produces the "Can't access procfs/sysfs file" error messages
| Philantrop wrote: | This is interesting. sensors is looking for another directory below /sys/class/hwmon/ which you don't have for reasons unknown:
| Code: | gentest ~ # ls -l /sys/class/hwmon/

|
Inside that directory, I have a symlink "device" which points to the actual device:
| Code: | gentest ~ # ls -l /sys/class/hwmon/hwmon0/
total 0
lrwxrwxrwx 1 root root 0 15. Jun 21:02 device -> ../../../devices/platform/i2c-9191/9191-0290
--w------- 1 root root 4096 15. Jun 22:35 uevent
|
|
I have nothing in the hwmon directory except "." and "..".

If so, we have to find the "missing link", so to speak, which would be the "hwmon0" directory. I have no idea yet what creates it. |
In my case, there is nothing related to i2c under /sys/devices/platform. lsmod produces this output, edited to remove things I knew didn't pertain:
| Code: | Module Size Used by
i2c_dev 13512 0
ns558 5952 0
radeonfb 112320 1
i2c_algo_bit 10632 1 radeonfb

sl811_hcd 15616 0
|
Anyone try one of the later "testing" kernels to see if this is fixed?

I'm in the same boat: Gigabyte GA-P945-S3, gentoo-sources-2.6.17-r8, lm_sensors-2.10.0. sensors-detect runs successfully and suggests the following modules:
| Code: | MODULE_0=i2c-isa
MODULE_1=eeprom
MODULE_2=it87 |
However, "sensors -s" and "sensors" both fail despite these modules being loaded:
| Code: | 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'! |
My "/sys/class/hwmon" directory is empty, too. My "/sys/devices/platform/i2c-9191" directory contains the following:
| Code: | | i2c-adapter:i2c-9191 name power uevent |
wherein "i2c-adapter:i2c-9191" links to "/sys/devices/platform/i2c-9191/i2c-adapter:i2c-9191", where "device/name" yields "ISA main adapter".
lspci says:

Specifically, there is an SMBus adapter.
Any idea anyone? |

Where are those? Under "ACPI Support", there's no such option, nor could I find anything like that in the ".config". I do have ACPI enabled, with modules for buttons, video, fan, processor (+ thermal zone). I figure this hint refers to "suspend" support, but I couldn't find that option either. In conclusion, I'm not sure this applies to current kernels any more (there's no CONFIG_ACPI_SLEEP option).
Applying the patch at
succeeds but doesn't seem to have any effect (yes, I did add the kernel command line parameter).

This appears to just change the text of the error message to:
| Code: | No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are. |
All modules suggested by "sensors-detect" are loaded (just as with the older version of lm_sensors). |

What version of kernel do you use? I'm using 2.6.18-suspend2
| Code: | $ cat .config | grep ACPI_SLEEP
#CONFIG_ACPI_SLEEP is not set |

Used to use gentoo-sources-2.6.17-r[78]; I have now upgraded to (unstable) gentoo-sources-2.6.18-r2 without any changes in this regard.

Yields nothing on my system. |

I'm experiencing same problem as you. Even with vanilla-sources-2.6.19_rc3
Gonna file a bug at http://bugme.osdl.org/ even after looking at http://bugme.osdl.org/show_bug.cgi?id=4391
If it happen that you fill the bug before me there please let me know. |

|

Had the same problem as the others: lm_sensors set up correctly, but no go and complaints about sysfs. On my mobo (Gigabyte P965-DS4) there is an IT8718F sensor chip, and according to the lm_sensors homepage supported hardware section, this chip is only supported by lm_sensors-2.10.1. Moreover, it is only supported by kernel 2.6.19 by default, as earlier kernels must be patched to run lm_sensors with this chip properly (patch provided on the page).
Solution: upgrade kernel 2.6.19-r2 and lm_sensors 2.10.1, both ~ARCH. This way, lm_sensors works like a charm, although the default readings a far from perfect, but hey, what is /etc/sensors.conf is for? Other good things are that with the kernel upgrade I got rid of the annoying "Port is slow to respond..." SATA-bug at boot, and this kernel finally supports the JMicron SATA/PATA Controller integrated to my mobo. |

thanks I think you finally put me on the right trial.
I'm trying to fix this in Kubuntu 2.6.17 with a gigabyte ga-965p-ds3 |
