After upgrading from Ubuntu 18.10 to Ubuntu 19.04 (Disco Dingo) the command /usr/bin/sensors -A no longer shows the fan information. Before upgrate I get this kind of information:

fan1:                      334 RPM  (min =    0 RPM)
fan2:                      864 RPM  (min =    0 RPM)
fan6:                     1076 RPM  (min =    0 RPM)
SYSTIN:                    +23.0°C  (high = +98.0°C, hyst = +95.0°C)  sensor = thermistor
CPUTIN:                    +27.5°C  (high = +80.0°C, hyst = +75.0°C)  sensor = thermistor
AUXTIN0:                   +23.5°C    sensor = thermistor
AUXTIN2:                   +23.0°C    sensor = thermistor
AUXTIN3:                   +97.0°C    sensor = thermistor
PECI Agent 0:              +30.0°C  (high = +98.0°C, hyst = +95.0°C)
PECI Agent 0 Calibration:  +27.0°C  
Core 0:        +27.0°C  (high = +80.0°C, crit = +100.0°C)
Core 1:        +33.0°C  (high = +80.0°C, crit = +100.0°C)
Core 2:        +30.0°C  (high = +80.0°C, crit = +100.0°C)
Core 3:        +29.0°C  (high = +80.0°C, crit = +100.0°C)

while after upgrade I get only this:

cpu_fan:        0 RPM

temp1:        +27.8°C  (crit = +119.0°C)

Package id 0:  +34.0°C  (high = +80.0°C, crit = +100.0°C)
Core 0:        +32.0°C  (high = +80.0°C, crit = +100.0°C)
Core 1:        +34.0°C  (high = +80.0°C, crit = +100.0°C)
Core 2:        +33.0°C  (high = +80.0°C, crit = +100.0°C)
Core 3:        +32.0°C  (high = +80.0°C, crit = +100.0°C)

I have the modules coretemp and nct6775 already declared into /etc/modules (same as for Ubuntu 18.10) and I also run sudo sensors-detect which also recommends those modules.

I have an Asus H370-I motherboard with an i3-8300 Intel CPU.

What is the problem and how should I solve it?


Editing /etc/default/grub and adding acpi_enforce_resources=lax to GRUB_CMDLINE_LINUX_DEFAULT might solve your problem.

So it looks something like this...

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_enforce_resources=lax"

I have read though that adding this may cause instability.
