Sensorsの監視内容がおかしい。
IBM鯖にいれたedubuntuを10.10から11.04にしてみたのはいいが・・・

Sensorsをインストールしてみたらsyslogに

なんて意味不明な値を記録する。
ちなみに設定は sensors-detect によって、自動的に行われたまんま既定値における現象である。
一般的に、センサーの未接続を検出するためには、「センサーの出力には、プルダウン抵抗ないしプルアップ抵抗を接続する」手法がとられる。
つまり、-128.0 Cという検出温度は未接続を意味すると考えるのが妥当であろう。
とりあえす、マニュアルを覗いてみることにして、
IGNORE STATEMENT
An ignore statement is a hint that a specific feature should be ignored
- probably because it returns bogus values (for example, because a fan
or temperature sensor is not connected). Example:ignore fan1
The only argument is the feature name. Please note that this does not
Manual page sensors.conf(5) line 90/415 27%
disable anything in the actual sensor chip; it simply hides the feature
in question from libsensors users.
という記述を見つけたので、ファイルの最後の方にある「adt7476」を検索して

とか、てきとーに書き換えてみた。
そして
sudo invoke-rc.d sensord restart
とかサービスのリスタートをかけてみると

ということで、マイナス百二十八℃は検出されなくなった。
でめたし。でめたし。
