2.6.10 upgrade

finidi · 01-16-2005, 03:00 AM

Until kernel 2.6.9-1.724_FC3 I was able to monitoring CPU & sys temps
using lm_sensors (MB Abit KT7-RAID) loading i2c-isa and via686a
modules. Then the upgrade to kernel 2.6.10-1.737_FC3 and now
when start the lm_sensors service I receive a "No sensors found!",
same with the more recent kernel 2.6.10-1.741_FC3. If booting under
the old 2.6.9 kernel the sensors come back. What has been changed ??
lm_sensors version is 2.8.7-2

Any gurus there ??

have you tried rerunning the detect program as root.

/usr/sbin/sensors-detect

Yes, I tried sensors-detect, and in fact it detects the most important sensor (CPU & sys temp.)
through the ISA bus:

Probing for `VIA Technologies VT82C686 Integrated Sensors'
Trying general detect... Success!
(confidence 9, driver `via686a')

after probes, all the necessary modules are loaded but running 'sensors -s' :

No sensors found!

I had to add /usr/sbin to the path (I did it in the sensors-detect perl script) or it didn't work with detecting stuff and then it worked.

Now resolved, it was a conflict between i2c-viapro and via686a modules... since 2.6.10 kernel ,the former is autoloadable by hotplug. I just put i2c-viapro in the hotplug blacklist and the sensors are readable again.

Kernel 2.6.11 fixes that conflict, then the 'blacklisting' will not be necessary.

sorry but i dont understand what you did.
i2c-viapro in the hotplug blacklist ?
in the terminal i only have
i2cdetect i2cdump i2cset

im using ubuntu.

I just simply included "i2c-viapro" in the blacklist file (/etc/hotplug/blacklist), but that it's not neccesary since kernel 2.6.11 ... if you use a recent ubuntu version the kernel is 2.6.15 or above, then the module conflict doesn't exist.
