It may be a hardware overheating issue. Did you install windfarm_core
and windfarm_fcu_controls to control the fans?
-Stan Johnson
I've enabled them since my upgrade to sid at the end of December but I
mentioned an other issue here yesterday :
https://lists.debian.org/debian-powerpc/2020/01/msg00062.html
I would really be surprised if it is an overheating issue and more if it
is a hardware problem (and I would be saddened...) . As I said, it
shutdowns randomly and sometimes very early after boot. With no
intensive task.
It has never occurred during Sid's installation process (I tried several
times).
With Wheezy, I doesn't occur either. And I do intensive tasks with it :
audio processing with ardour, parallel builds with both cpus and so on.
The temperature of my cpu does only increase from 55°C to 67°C doing
that. My SSD is 37°C and my HD is 44°C now.
I will monitor those temperatures with sid.
As John Paul suggests, I will try different kernels. First, can I try
Jessie's kernel in Sid or will it be a problem with my ext4 root
partition ? I'll try to build more recent kernels after that.
Thanks for your kind answers.
