I am new to this forum, but not to Debian nor the Linux users world. I've been using various distros since 2007, including Debian from time to time.
But since some weeks, I have a crazy long boot time I can't explain, even after googling the problem. I think I am mislead by the ACPI error message, that seems to be a common bug with no impact on performances.
I do have some systemd networking.service problem I could solve. But my kernel time is long and I can't figure out why. Could you please help me figuring out why?
Here is the startup screen:
Systemd-analyze output:
