Red Hat Bugzilla – Bug 213357
Last modified: 2015-03-04 20:17:52 EST
Description of problem: lm_sensors works with fc6xen kernel but not with plain
fc6 (2.6.18-1.2798.fc6 #1 SMP) kernel on the same system&hardware (Asus P4PE-X,
Intel 845PE, Intel P4 2,4GHz/512 Northwood/HyperThread, 512MB, Video ASUS V9180SE)
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install FC6.
2. With xen kernel, sensors-detect properly detech hw & sensors works
3. When rebooted with plain kernel, sensors-detect & sensors are failing (Only
unsupported Nvidia sensor found)
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
(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.
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'!
< lots of hardware sensor info as with xen kernel>
sensors-detect worked for me with RHEL 3.x, 4.x and 2798.fc6xen, but for some
reason sensors-detect fails from 2798.fc6. When I try to load modules detected
in with xen kernel eg:
sensors still shows error message as shown before.
Short introduction, I'm a Fedora contributer and since I'm involved in
lm_sensors upstream, I've also become a co-maintainer of lm_sensors in Fedora.
I think your problem is that you lm_sensors is too old to work with newer kernels.
lm_sensors-2.10.1-1 is available from FC-6 updates.
You may also want to try and update your kernel.
Please let me know if this helps.
I realize we (Fedora) have taken a long long time to respond, but now I would
really like to move forward with this bug. Can you please try with the latest
kernel and lm_sensors. If you no longer have the machine involved, then please
say so and I'll close this bug.
(In reply to comment #2)
I reported this bug almost year ago, and I strongly believe that it is gone by
now, especially because that was the very first FC6 release if I remember
correctly. Anyway, because I really appreciate Fedora's efforts, I can find my
old machine, install FC6, apply latest updates, and report you back if it helps
as soon as I find some time, ---OR--- you can close it if you want because that
MOBO is definitely thing of the past. You choose.
I think digging up the old machine and installing FC-6 et all is a a bit over
the top for something that is likely fixed, so I'll close this. If you ever dig
up the old machine for another reason it would be great if you could test this.
(testing with F-7 will be fine too).
I found my old machine: FC6 with buggy sensors was still there, untouched!
After kernel & sensors update (2.10.0 -> 2.10.1-1, 2.6.8-1.2849-fc6-SMP ->
latest) I can confirm that the asb100 bug is definitely gone.
