Proxmox 6.8.12-9-pve kernel has introduced a problem with network connection - enp0s31f6 Intel NIC

[leandrosgf]

Hello All,

Has anybody experienced problems with the enp0s31f6 Intel network card with the new Proxmox VE 6.8.12-9 Kernel?
With this new kernel, the network suddenly stops after some hours. I don't seem to see any relevant information that I can explore.
I don't have the same behavior using the pinned 6.8.12-8-pve Kernel.

Thank you!

I don't know if it is relevant, but after the last 3-4 updates my Proxmox 8.3.5 stops responding on the network when the backup starts.
When I pull and put back the ethernet cable, the connection is restored, only the backup fails.
I have here two almost identical systems. One is fully up to date and hangs. The other list a bunch of updates, but is NOT freezing during backup.
One of the things offered is the new Kernel. See screenshot.

Interesting, I will keep watching it and check If I can see ithis same behaviour.
Looking at other threads it vould be something wrong with E1000 driver and this specific new kernel.

Thanks for your comments!

There is a way to revert to the previous kernel version, but I am no linux pro. I need to check it out a bit more.

Me neither, but you can easily do it using this way:
1. First, list your available kernels with the command # proxmox-boot-tool kernel list
2. Once you have a list of your available kernels, choose one and copy the name of this kernel ( in my case, I used the "6.8.12-8-pve" )
3. Finally, pin your kernel for the next boot using this command:# proxmox-boot-tool kernel pin 6.8.12-8-pve --next-boot

You can unpin the kernel and go back to the latest one anytime using the command: # proxmox-boot-tool kernel unpin

Hi and yeah, I had phind.com those steps already and had them ready to use in my notes. Thanks anyway.
The conclusion is that it worked. I am on the same "old" 6.8.12-8-pve kernel and the backup went on as usual. No hiccups, no network problems.
Thanks for pointing me to the kernel.

Same behaviour here. Network card is up but no connectivity (Intel I217-LM controller). I must disconnect and reconnect the network cable and then network access is reestablished.
Issues begin after last kernel update.
I've just reverted kernel to 6.8.12-8-pve , thanks @leandrosgf , will see if issues are gone.

Just FYI, I have two network adapters on the board 1+2.5Gb
Intel Corporation Device 0dc8 (rev 11) I219V - 1Gb (connected)
Intel Corporation Ethernet Controller I226-V (rev 04) - 2.5Gb disconnected/not used)
on a ASRock Z790M-ITX WIFI motherboard.
The second backup went just fine today, so I can confirm that the Kernel downgrade helped.
