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 GNU/Linux and systemd 257 (257.2-1)
