log file shutdown
Hello all,
sorry for my bad English
here I am installing an archlinux32bits on an old laptop (Acer Aspire 1680).
Everything works startup, reboot, wifi, touchpad etc ... except the shutdown of
the pc which is incredibly long.
I managed to copy the messages that are displayed before the shutdown of the
laptop:
INFO: task shutdown:1 blocked for more than 120 seconds.
Tainted: G W 4.19.81-1.0-lts #1
"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

This problem is no longer present by compiling the kernel 3.16.78 (recovered on
https://www.kernel.org). I tested the compilations of several kernel 4.x and
5.x but this problem comes back.
Do not hesitate to ask log or other files to try to allow me to understand
where the problem lies.
I performed a debug of the system shutdown by following the instructions of
https://freedesktop.org/wiki/Software/systemd/Debugging/#Diagnosing_Shutdown_Problems
and i attach the result file.
