[Pkg-acpi-devel] Bug#784157: acpid: Fan does not run on fresh install of Jessie

[Glen Reesor]

Package: acpid
Version: 1:2.0.23-2
Severity: critical
Justification: breaks the whole system

Dear Maintainer,

On a fresh install of Jessie on an Acer Aspire 5720Z laptop, the fan never
runs. As a result, system overheats and shuts down in non-graceful way.

I have installed lm-sensors, run sensors-detect, and added the module
suggested (coretemp). It didn't help.

While trying to debug this, I've noticed that the temperature reported
by sensors has three values, only 2 of which change:

    acpitz-virtual-0
    Adapter: Virtual device
    temp1:        +40.0°C  (crit = +100.0°C)   <----- Does not change

    coretemp-isa-0000
    Adapter: ISA adapter
    Core 0:       +63.0°C  (high = +100.0°C, crit = +100.0°C)
    Core 1:       +66.0°C  (high = +100.0°C, crit = +100.0°C)

Given that this is a dual core cpu, I'm guessing that Core 0 and Core 1
correspond to cpu temperatures. I'm also wondering if acpid is watching
the temp1 (40C) value, which is why the fan never turns on.
