[Bug 475641] [NEW] pwmconfig does not work after upgrade to 9.10 on TYAN server

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

Prior to upgrading from 9.04 to 9.10 I had configured
pwmconfig/sensors/fancontrol so that the cooling fans on my servers were
not too loud.  I have 2 TYAN Transport GX28 servers with Tyan Thunder
K8S Pro S2881G2NR motherboards, which have the latest BIOS updates from
TYAN.  These are 1U servers, which have very loud fans.  I am using them
outside of a rack in my home, and they stayed cool with fans running at
about 1/3 the maximum default speeds.  After upgrading to Ubuntu version
9.10, the fans are now running very loud again.  When I run sensors, I
get only the basic k8temp CPU temperatures and do not get the long
version of the output that showed fan speed, temp, or voltage sensors.

--------------------------------------------------------------------------
I tried to run pwmconfig again to configure the '/etc/fancontrol configuration file, but I get an error that says:

         /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed
--------------------------------------------------------------------------
I ran /usr/sbin/sensors-detect and it said the following: 
         Driver `w83627hf' (should be inserted):
            Detects correctly:
                * ISA bus, address 0x290
               Chip `Winbond W83627HF/F/HG/G Super IO Sensors' (confidence: 9)

         Driver `k8temp' (should be inserted):
            Detects correctly:
              * Chip `AMD K8 thermal sensors' (confidence: 9)

       I will now generate the commands needed to load the required modules.
       Just press ENTER to continue: 

       To load everything that is needed, add this to /etc/modules:
 
          #----cut here----
          # Chip drivers
            w83627hf
            k8temp
          #----cut here----

     Do you want to add these lines automatically? (yes/NO)y

I have also tried a reinstall of lm-sensors that did not help.
     lm-sensors:
        Installed: 1:3.0.2-2ubuntu4
        Candidate: 1:3.0.2-2ubuntu4
        Version table: 1:3.0.2-2ubuntu4 0

I get the following error reported for ACPI by dmesg

--------------------------------------------------------------------------
On one of my servers the /boot/grub/menu.lst still had the option to load the 2.6.28-16 kernal image.
When I booted with this prior kernel image, the pwmconfig and fancontrol worked correctly and 
and sensors produced the output in the attached "sensors.log" file.
With the current 2.6.31-14 kernel, sensors only reported the first 6 lines for CPU temp.

--------------------------------------------------------------------------
I have tried to edit menu.lst on my second server, but it no longer has the
old kernel available, and I cannot figure out how to load it. 

I tried to run:
      sudo apt-get install linux-image-2.6.28-16-generic
but got the following:

Package linux-image-2.6.28-16-generic is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package linux-image-2.6.28-16-generic has no installation candidate


--------------------------------------------------------------------------

This is my first bug report.  I am sorry if I have been given your too much or 
too little information.  

Please let me know if I can provide any other information that you need.


Thanks,
Greg
