1 Hi,
2
3 The configuration for kernel 5.6.3. (vanilla) works fine.for me.
4 Then I changed to kernel 5.6.4 using the same configuration.
5
6 Suddenlu the fan at the back of my PC case never stops from
7 rotating at its highest speed.
8 Changing back to kernel 5.6.3. and the problem is gone.
9
10 On the internet I found one report of a fan problem after
11 an upgrade of Ubuntu...but that was 5 years ago...
12
13 I compared the entries in /sys/devices/platform/nct6775.2592/hwmon/hwmon1/*
14 between the two kernels but found nothing obvious.
15
16 The CPU temperature was around 45° C in both cases.
17
18 Waiting does not help also...
19 (in case kinda 'settling time' has changed...or so...)
20
21 Is there any other place to investigate?
22 What could be the root of this?
23
24 Cheers!
