lm-sensors and w83627hf module problem

[staffann]

I recently installed Ubuntu 9.10. I'm trying to use lm-sensors and the sensors-applet to see a number of things measured hardware valuue but I'm having some problems.

I first ran the command sudo /usr/sbin/sensors-detect. It detected two modules that were added to the /etc/modules file:

# Generated by sensors-detect on Sun Dec 6 14:49:30 2009
# Chip drivers
w83627hf
k8tempThe k8temp module seems to work but w83627hf doesn't. If I issue the command "sensors" this is all I get:

staffan@bilbo:~$ sensors
k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp: +54.0°C
Core1 Temp: +51.0°C Doing a lsmod gives me a list of moduls and w83627hf isn't among them:

staffan@bilbo:~$ sudo lsmod

Finally issuing the modprobe command fails:

staffan@bilbo:~$ sudo modprobe w83627hf
WARNING: All config files need .conf: /etc/modprobe.d/ndiswrapper, it will be ignored in a future release.
FATAL: Error inserting w83627hf (/lib/modules/2.6.31-16-generic/kernel/drivers/hwmon/w83627hf.ko): Device or resource busy
What can I do to make it work?

I just solved this problem myself, by following the instructions here (http://ohioloco.ubuntuforums.org/showpost.php?p=8485676&postcount=10).

[staffann]

That works! Thanks!! :D
But what does that command (GRUB_CMDLINE_LINUX="acpi_enforce_resources=lax") mean?

[Rastor]

This is needed because of a safety feature which was implemented in the 2.6.31 kernel:

http://www.lm-sensors.org/wiki/FAQ/Chapter3#Mysensorshavestoppedworkinginkernel2.6.31

Altering the GRUB_CMDLINE_LINUX line is how you modify the Linux kernel boot commandline in Grub 2.0 (which is used by Ubuntu 9.10 as the bootloader).

Thanks for the link!
