Description Joe Acosta 2004-07-15 01:38:50 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7) Gecko/20040616

Description of problem:
Run sensors-detect

 Now follows a summary of the probes I have just done.
 Just press ENTER to continue:
Driver `eeprom' (should be inserted):
  Detects correctly:
  * Bus `SMBus Via Pro adapter at 5000' (Algorithm unavailable)
    Busdriver `i2c-viapro', I2C address 0x50
    Chip `SPD EEPROM' (confidence: 8)
  * Bus `SMBus Via Pro adapter at 5000' (Algorithm unavailable)
    Busdriver `i2c-viapro', I2C address 0x51
    Chip `SPD EEPROM' (confidence: 8)
Driver `via686a' (should be inserted):
  Detects correctly:
  * ISA bus, undetermined address (Busdriver `i2c-isa')
    Chip `VIA Technologies VT82C686 Integrated Sensors' (confidence: 9)

Then run sensors and I get
No sensors found!

modules are loaded though 

via686a 17480 0 - Live 0xe091f000
i2c_sensor 2368 1 via686a, Live 0xe08ed000
i2c_viapro 4940 0 - Live 0xe08c0000
i2c_isa 1664 0 - Live 0xe08d9000
i2c_core 18516 5 i2c_dev,via686a,i2c_sensor,i2c_viapro,i2c_isa, Live
pl2303 14084 0 - Live 0xe0900000

Version-Release number of selected component (if applicable):
kernel 2.6.5

How reproducible:

Steps to Reproduce:
1. run sensors-detect
2. run sensors
3. make sure modules are loaded.  This used to work in fedora core 1

Comment 1 Joe Acosta 2004-07-22 23:41:03 EDT
It seems that both the i2c_viapro and i2c_isa modules get loaded as
well as the via686a module.  According to the lm_sensors web site the
via686a module NO longer works with i2c_viapro, however it used to in
kernel 2.4.  I am not sure that this will be fixed or if it will
remain a bug.  Sensors seem to be working again though after removing
the i2c_viapro module and reloading the via686a module.

Comment 2 Phil Knirsch 2004-10-18 12:03:10 EDT
Did you give newer versions of the lm_sensors package a try to see if
it has been fixed already upstream?

I mean, if they know that a certain combination won't work it
shouldn't be that hard to do the right thing then.

Read ya, Phil
Comment 3 Joe Acosta 2004-10-18 12:40:45 EDT
I do run up2date, so if there is a new package in up2date then I have

However I also have removed the i2c_viapro module from my kernel (
recompiled without it).  Since it is working, I have not retried.  I
only use the sensors to run the wmsesnsors applet to get an idea of if
my CPU is overheating or not.   
Comment 4 Matthew Miller 2005-04-26 11:27:16 EDT
Fedora Core 2 is now maintained by the Fedora Legacy project for
security updates only. If this problem is a security issue, please
reopen and reassign to the Fedora Legacy product. If it is not a
security issue and hasn't been resolved in the current FC3 updates or
in the FC4 test release, reopen and change the version to match.
Comment 5 Joe Acosta 2005-04-26 11:52:43 EDT
You can close this.  I've upgraded to FC3 and my sensors are working fine. 
Except my sensors applit which crashes, but that's another issue.
