Hello.

I want to expose a problem I have met with pwmconfig.

With ubuntu 10.11, the pwmconfig complains there is no
available system for monitoring the cpu fan.

With the last kernel in Archlinux, I have the same problem.
With the LTS kernel in archlinux (3.0), the problem
disappears, everything works fine.

I cannot understand why with the 3.0 kernel, I have a bug in ubuntu
and not in archlinux (because the API should not to be broken).

In archlinux it is the two following versions :

local/linux-lts 3.0.17-2
local/linux 3.2.2-1 (base)

In ubuntu 10.11, the kernel is :
  3.0.0-15-generic-pae #26-Ubuntu SMP Fri Jan 20 17:07:31 UTC 2012 i686 
i686 i386 GNU/Linux

When it fails, it seems that the coretemp interface is loaded, and I can 
see the cpu temp
in both cases (when fancontrol fails and when it doesn't fail), but only 
the cpu temp.

When it doesn't fail, I have another interface which manage all the 
sensors of my motherboard,
including the control of fans (I can have up to 4 fans controlled). I am 
going to be a bit
approximative, but the interface being loaded when it works is called 
"netxxxx" where the "xxxx"
is some number. I could tell you more about this point the next time I 
boot the archlinux LTS kernel.

My motherboard is H67 chipset :

I hope this helps to solve my problem

Thank you very much.
