networking.service fails
Dear Debian community,
I am puzzled with the following problem. When my Debian 10.8 starts, the unit "networking.service" is
marked as failed with the following reason:
root@debian:~ # systemctl status networking.service
*— networking.service - Raise network interfaces
Loaded: loaded (/lib/systemd/system/networking.service; enabled; vendor preset: enabled)
Active: failed (Result: exit-code) since Tue 2021-02-16 08:56:16 CET; 5h 27min ago
Docs: man:interfaces(5)
Process: 691 ExecStart=/sbin/ifup -a --read-environment (code=exited, status=1/FAILURE)
Main PID: 691 (code=exited, status=1/FAILURE)
however network is working just fine. I looked into /usr/lib/systemd/system/networking.service where
TimeoutStartSec=5min
and also set a big timeout for br0 in /etc/network/interfaces:
auto lo
auto eth0
auto eth1
iface lo inet loopback
auto br0
iface br0 inet static
...
bridge_ports eth0 eth1
bridge_maxwait 60
but still the error occurs each time. Relative dmesg logs are:

Any ideas where can I take a look? Thanks in advance!
