lm_sensors driving me insane

I've tried just about everything to get this thing working. The problem I'm stuck on is:

# 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'!

sensors-detect finds the chips, and I've written what it tells me to. I've tried unmerging and re-merging it, no luck. sysfs and procfs are both in my fstab:

Code: Select all

procfs              /proc           proc            defaults        0 0
sysfs               /sys             sysfs           defaults        0 0

Pretty much every single module has been selected and compiled (modules, not built-in). Any help would be greatly appreciated. Thanks

*pulls hair out*
Oh, this is an emachine laptop on a via chipset. AMD64 Gentoo 2006.0.

but is sysfs actually mounted? if you just type "mount", it should look like this:

Code: Select all

proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)

we have lm_sensors running on amd64 fine.

btw.. you did run "/etc/init.d/lm_sensors start"?

Both sysfs and procfs are mounted.

Code: Select all

/dev/hda6 on / type ext3 (rw,noatime)
procfs on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
udev on /dev type tmpfs (rw,nosuid)
devpts on /dev/pts type devpts (rw)
shm on /dev/shm type tmpfs (rw,noexec,nosuid,nodev)
usbfs on /proc/bus/usb type usbfs (rw,devmode=0664,devgid=85)

lm_sensors start loads the modules, then proceeds to fail on the sensor start.

Code: Select all

# /etc/init.d/lm_sensors start

which says:

are you sure your chipset is supported by lm_sensors at all? check out their website.

TBKDan · Post by **TBKDan** » Mon Apr 24, 2006 3:27 pm

I did that after my last post, and it still does not recognize any sensors. sensors-detect finds the bus and chip, and via chipsets are supported according to the lm_sensors webiste.

EDIT: Misread your last post. I modprobed i2c-isa. When doing sensors-detect, I was saying yes to everything to let it find everything it could

TBKDan · Post by **TBKDan** » Tue Apr 25, 2006 3:07 pm

I just upgraded to 2.6.16-r3. Still nothing new =/ Everything is compiled as a module. Anybody have any ideas?

TBKDan · Post by **TBKDan** » Sat May 06, 2006 6:06 pm

Ok, I just got my laptop back from repairs (Vid card fried), and I'm back to where I was. I still have no clue how to get this running... how should the proc and sysfs look in fstab? Is there anything else I'm missing?

Anyluck on this mysterious problem? Mine are the same, the modules show to be loaded, even when they aren't and you run /etc/init.d/lm_sensors start they load but fail to intialize. Then if you do sensors they give the error about accessing /proc and /sys. Rank this right up there with being as annoying as glxinfo's can't handle tls data issues.

EDIT:

Just found out that i have no /sys entry in my /etc/fstab, but sys seems still to be mounted?
is this normal with newer kernel versions or udev versions?
Maybe thats the problem ...

Have you by any chance updated to vanilla-sources-2.6.17_rc5?

There appears to be a bug affecting sensors.. rc4 works ok, rc5 doesn't.
I haven't discovered why yet & the .configs are identical.

slycordinator · Post by **slycordinator** » Fri Jul 14, 2006 10:18 pm

Not sure how to fix this but if you look at the init script, it refers to /proc/sys/dev/sensors

I'm assuming this is what the "sensors" program is looking for when it is being called. And on my box that file doesn't exist.

I have i2c-core, i2c-core, i2c-algo-bit as built-in and eeprom and i2c-i801 as modules.

Does anybody know about libsensors?

When running sensors it says make sure libsensors is compiled with sysfs support.

Also if I run " strace -s500 sensors -s >sensors_debug 2>&1" I get this errors about:

/usr/local/lib/tls/i686/sse2/libsensors

If I look in /usr/local/lib I don't see the tls directory at all, anybody else notice this?

Same here with a Centrino
there's nothing in /sys/bus/i2c/devices either, that's probably where it comes from.
