High per­for­mance sys­tem usu­ally need to be tem­per­a­ture mon­i­tor­ing every­day to pre­vent­ing from hard­ware fail­ure by the over­seed­ing heat trap. In Win­dows mode like Win­dows 7 or Vista, we don’t found­ing hard prob­lem with hard­ware mon­i­tor­ing soft­ware but some­how we must spent extra­time to patch for work­ing expe­ri­ence in open­source oper­at­ing sys­tem like linux does.

Many Linux dis­tri­b­u­tion still using same low level dri­ver mon­i­tor likes lm_sensors for super i/o hard­ware mon­i­tor­ing read­out. We can using 3^th party linux dis­tri­b­u­tion pack­age help for GUI (graph­ics user inter­face) win­dows mode if you like some eye­candy in your desk­top. The prob­lem appears in new 2.6.31 ker­nel if we work­ing with it87  dri­ver in lm_sensors configuration

$ mod­probe it87

FATAL: Error insert­ing it87 (/lib/modules/2.6.31.8–0.1-desktop/kernel/drivers/hwmon/it87.ko): Device or resource busy

There is kindly like lit­tle buggy ker­nel ACPI dri­ver con­flict that must reg­is­tered first from BIOS code.

For Linux oper­at­ing sys­tem and test­ing i using Open­suse 11.2 x64 that upgrad­ing with 2.6.31.8–0.1-desktop ker­nel.
… And here a sim­ple step for answer­ing the problem

1. Down­load and install lm_sensors dri­ver and 3^th party pro­gram if u like

$ sudo zyp­per in sen­sors gkrellm ksensors

2. Con­fig­ur­ing them with (root console)

$ sensors-detect

Shut­ting down sen­sors: done

# sensors-detect revi­sion 5729 (2009−06−02 15:51:29 +0200)

# Sys­tem: BIOSTAR Group TPower I55

This pro­gram will help you deter­mine which ker­nel mod­ules you need to load to use lm_sensors most effec­tively. It is gen­er­ally safe

and rec­om­mended to accept the default answers to all questions, unless you know what you’re doing.

Some south bridges, CPUs or mem­ory con­trollers con­tain embed­ded sensors.

Do you want to scan for them? This is totally safe. (YES/no): y

3. Put my sen­sors code if you have the same moth­er­board in /etc/sensors3.conf or you can cus­tom name for dif­fer­ent sen­sors source. You can com­pare your source sen­sors from win­dows based soft­ware mon­i­tor­ing or from the Bios itself
