From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040124 Description of problem: lm_sensors version 2.8.3-4 does not seem to install libsensors or one of its components since all temperatures can not be read. This is ticket number 1591 at lm_sensors support: http://secure.netroedge.com/~lm78/readticket.cgi?ticket=1591 2.8.4 is out and i was told the RPM should be updated to that newer version. Version-Release number of selected component (if applicable): lm_sensors-2.8.3-4 How reproducible: Always Steps to Reproduce: 1. install lm_sensors 2. run detect-sensors 3. run sensors -c 4. run sensors to see results Actual Results: temperatures can't be read Expected Results: temperatures should be read Additional info: Please upgrade to version 2.8.4
Who from which support told you this is a libsensors/sensors mismatch? I think it's highly unlikely as lm_sensors updates both, sensors and libsensors at the same time, so a mismatch is nearly impossible. I'll update to 2.8.5 as soon as that is released, hopefully that will fix the problem you're seeing. Read ya, Phil
I posted a support request ticket at the lm_sensors website: http://secure.netroedge.com/~lm78/readticket.cgi?ticket=1591 I am not sure who replied, but it must be one of the admins. Maybe this particular rpm was broken and didn't update both sensors and libsensors? Anyway, i'll wait for your 2.8.5 release to test.
OK. As i said, the lm_sensors package updates both sensors and libsensors. Are you using the lm_sensors initscript by any chance? Because with the latest 2.6 kernel that doesn't work anymore. I just updated that script to work correctly again. If you like you can give lm_sensors-2.8.3-5 or later a shot which should be available in the next few days. Read ya, Phil
No i'm not using the initscript of lm_sensors, and i'm at the latest 2.4 kernel. I'll try the newer version when it comes out.
I've been told that lm_sensors 2.8.5 has the fix to make lm_sensors work again on my system, i've checked the changelog and it seems the it87 driver for my system has had many updates. I'll try the 2.8.3-5 just in case though.
I updated to 2.8.3-5 and i still can't get any temperature readings, as stated above i get these errors: ERROR: Can´t get TEMP1 data! ERROR: Can´t get TEMP2 data! ERROR: Can´t get TEMP3 data! Please update lm_sensors to 2.8.5.
A new lm_sensors 2.8.6 package will be built today. Please give that one a shot. Thanks, Read ya, Phil
Could you please tell me where to download 2.8.6 from? i've been trying to find the file without success in the http://download.fedora.redhat.com/pub/fedora/linux/core/ file structure, but all i can find is 2.8.3 or older versions.
It should appear in the next couple of days here: http://download.fedora.redhat.com/pub/fedora/linux/core/development/i386/Fedora/RPMS/ Read ya, Phil
Just tested version 2.8.6 and i'm having the same problem. I think this is related to the recent changes in the it87 driver, which probably broke some sensors. I've tried to get help from lm_sensors people but they are avoiding the issues by giving the typical excuses. Anyway, i dont think this is a fedora/redhat problem.
After long hours of debuging and testing, i've come up with the same initial results. the rpm package does not update the sensor modules. under /lib/modules/2.4.22-1.2174.nptl/kernel/drivers/sensors the sensors are the old/original 2.6.5. the rpm package does not include the new versions of the sensors and since the old versions don't support the new libsensor interface, they break compatibility.
hmm after some careful discussion with Jean Delvare from lm_sensors mailing list, we've realised that the lm_sensors package only updates the user-space tools and not the kernel modules. thats... erm well, sort of pointless, since every time the user space tools are updated, the kernel modules must be updated too! otherwise this is what happens, they can't communicate correctly. in other words, only a kernel update will solve this problem, and i also think that the lm_sensors package should only be updated when a new kernel comes out, in order to avoid breaking things (so both kernel and user-space modules are the same version).
Unfortunately we have a strict rule that no userland tool may build and install any kernel modules. So if you want to have the latest drivers for lm_sensors then you also need to update to the latest kernel (one of the 2.6.5 series), otherwise you certainly won't have the latest drivers.
