State change stops working #12

Hello, it appears the state change stops working sporadically in my case. I am using version 1.43.

Here is my log output:

Note the last entry for Jun 08 00:11:49. From there on it is stuck in state 2. Under heavy load my system just shuts down. It also happens in the opposite direction, ie. when the temp goes down the fan stays in state 3.

I am using SMM with a patched dell-smm-hwmon kernel module on a Vostro 3300 (right fan only).

Thank you for maintaining i8kutils. It has served me and my ears well for years!

The config from the previous post was an attempt to fix the issue. Up until then I was using the following:

set config(0)   {{-1 0} -1  50  -1  50}
set config(1)   {{-1 1} 40  85  40  85}
set config(2)   {{-1 2} 75  128 75  128}
set config(3)   {{-1 2} 75  128 75  128}
