Hi forum,

anyone seen this before:

I keep getting lots and lots of these lines- no idea where they come from.
Any idea where to look?



Thanks beforehand,

I feel this message might be from LM sensors which senses the temperature
see the link1

Hello Dr Kurian

thanks for the hint- yes, you're right, seems like the errors stem from there.
After installing package lm-sensors I get the following output:

But how do I get rid of this flood of error messages filling up my logfiles?
Can I disable certain sensors?
