i have Fedora 35 running on a DELL Precision 3640. Yesterday i did a firmware upgrade through Gnome Software. Included in the Update was a newer BIOS, an Upgrade to the Intel ME Firmware and a fix for INTEL-SA-00459. After the Upgrade everything worked fine for the day, but today after doing regular Fedora updates, my integrated ethernet adapter has gone missing. Even after booting from a normal Fedora Workstation 35 Live ISO, the adapter is still not showing up.
I don’t think it’s down to the updates i installed today, because the adapter also doesn’t work in the Workstation Live System.
Attaching a USB to Ethernet Adapter worked, i got the machine online for now. But that isn’t the optimal way to do things and i would really want to get the internal adapter working again.
Some things i was able to find out by myself:
The adapter DOES NOT show up in Gnome Settings, using ip a or in the folder /sys/class/net/
I can still look at the old network profile using nm-connection-editor
Looking through dmesg, this is what i get when searching for the adapter:
[ 1.275774] e1000e: Intel(R) PRO/1000 Network Driver
[ 1.275775] e1000e: Copyright(c) 1999 - 2015 Intel Corporation.
[ 1.275976] e1000e 0000:00:1f.6: Interrupt Throttling Rate (ints/sec) set to dynamic conservative mode
[ 1.524159] e1000e: probe of 0000:00:1f.6 failed with error -3
I also tried to do some troubleshooting, but none of it worked so far:
Enable the Fedora Testing Repositories and pull updates from them: installed a new kernel, but didn’t change the behaviour of the system
Play around with some of the BIOS settings like Secure Boot and Internal NIC settings: no change
Downgrade the BIOS to the version i was on before: Nope, didn’t do anything.
The really interesting thing: My colleague has the same system and also did the firmware upgrade, but his Workstation uses the Network Adapter I219-LM instead of the I219-V i have - his system works fine, even after updating Fedora to the latest state.
Im really close to the end of my knowledge here, but i still have some hope for getting the adapter working again. Does somebody have an idea on how to do that?
