 |
|
Hello,
I've been having a problem with lm92 not reading the temperature of my cpu. This module was suggested by sensors-detect, but I tired modprobing all the lm* sensors. Lm92 loads fine as does lm_sensors, but reads a temperature of zero degrees. I know the problem does not lie with acpi because I've talked to devs on their mailing list and they explained the new way to build a dsdt file and that one compiled fine.
There are some missing modules, but patching the kernel is becoming a pain:
| Code: | * Loading lm_sensors modules...
* Loading i2c-i801 ... [ ok ]
* Loading eeprom ... [ ok ]
* Loading smbus-arp ... [ !! ]
* Loading smartbatt ... [ !! ]
* Loading saa1064 ... [ !! ]
* Loading lm92 ... [ ok ]
* Loading pca9540 ... [ !! ]
* Loading max6650 ... [ ok ]
* Initializing sensors ... [ ok |
Max6650 so far is the only module I've added by hand, but I've tried with pca9540 (pca954x) but the patch floating around isn't working. I've read through the documentation, but it's a little over my head.
Also, smbus seems to be going nuts in my dmesg:
| Code: | | i2c_adapter i2c-0: smbus word data - addr 0x4f, read 0x0000 at 0x02. |
It reads alll of the sys bus files over and over again.
My computer is a Dell Dimension 8250. I couldn't find any information about what sensor it uses.
I appriciate any help,
John

Is that what is preventing me from getting any temperature readings?

When any module in the lm_ prefs fails to load, the LM_sensors daemon quits. It stops running, and you get no readouts. Comment it out of the prefs, and renumber the module numbers to skip over the ones you comment out.
/etc/conf.d/lm_sensors
| Code: |
# Generated by sensors-detect on Fri Apr 7 21:20:29 2006
# Load modules at startup
LOADMODULES=yes
# Initialize sensors at startup
INITSENSORS=yes
MODULE_0=i2c-amd756
MODULE_1=i2c-isa
MODULE_2=lm90
MODULE_3=eeprom
MODULE_4=w83627hf
#MODULE_5=smbus-arp
#MODULE_6=pca9540
|
For whatever reason, several moduals which lm_sensors NEEDS don't even exists in production kernels, and have been missing for 2 YEARS already. Comment them out. |

I commented out the bad modules and renumbered so I get the following:
| Code: | * Loading lm_sensors modules...
* Loading i2c-i801 ... [ ok ]
* Loading eeprom ... [ ok ]
* Loading lm92 ... [ ok ]
* Loading max6650 ... [ ok ]
* Initializing sensors ... [ ok ] |
Unfortunately, still no readout on the temp sensor and I still am getting a million dmesg smbug word data messages.
I appriciate the relies,
John
