Package: network-maager
Version: 1.50.1-1
This system has a dual 10G NIC (i40e) which is not connected to anything, it has
a loopback cable for testing but is not used for normal networking. It is marked
disabled in network-manager
It also has a dual 2.5G NIC (igc) and one port is connected to Internet via
Ethernet switch.
When system boots, the network now comes up correctly.
But after suspend/resume the networking is broken; looks like network manager
(or systemd or some other script) has decided to bring up the 10G interfaces
but not the one 2.5G NIC.
If I blacklist the i40e module, that works on boot; but again on suspend/resume
some part of the process decides to reload the i40e module and try and bring up
the 10G interfaces.
The workaround is on resume:
$ sudo rmmod irdma i40e
$ sudo rmmod igc
$ sudo modprobe igc
And then the port will come back.
This is on current Debian testing.
Linux 6.12.9-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.12.9-1 (2025-01-10) x86_64

That looks like a kernel / driver problem. So I'm tentatively closing
this issue against network-manager.
