Description Ionut Nechita 2020-11-29 19:27:37 UTC
Hi OpenSUSE Team,

I used this iso image so I can do an installation on a system. 
http://download.opensuse.org/tumbleweed/iso/openSUSE-Tumbleweed-NET-x86_64-Current.iso.
Upon detection of the system, the modules were loaded, but I did not have a network in the installer.
The network controller is: I210 Network Gigabit. ( igb driver )
The igb driver module was loaded but I did not see the active interface( eno1 / enp2s0 ).

With the "ip a" command, in the expert shell ( network image ), only the local interface( loopback ) was seen.

I will test more the next few days, and I will add more logs.


I210 Network Controller, igb driver, NET image, DHCP Server Enabled.

I tested it with an older bios, and I think that's why the problem was reported.

I used a kernel boot parameter for this workaround.
Kernel parameter inserted in GRUB: pcie_pm_port=off

With this parameter, the board was recognized in the installer.

Thanks for support.

Hi OpenSUSE team,

My BIOS contains a small bug.
It can be fixed by an update, but I will not do it, because it is a critical system.

It's fine to close this ticket.

I stumbled over this bug as well. This is openSUSE Tumbleweed 20210209 with an

Ethernet controller: Intel Corporation I211 Gigabit Network Connection (rev 03)

using the igb-Kernel driver. Kernel 5.15.6-1 default.
