Hi,

today, 2020-08-04, after the kernel upgrade, from initrd.img-5.4.41-1-pve to initrd.img-5.4.44-2-pve, and a reboot,
all NIC of the "DMI: Supermicro Super Server/X11SPM-F, BIOS 3.2 10/18/2019 " are down.
There are two RJ45 1Gbit/s NICs (and not one 10 GBit NIC).
As in this thread: https://forum.proxmox.com/threads/error-i40e_aq_rc_enospc-forcing-overflow-promiscuous-on-pf.62875/
I get the Errors in the syslog:
Code:
...

...
The Network driver i40e is version 2.8.20:
Code:
 # modinfo i40e 
filename:       /lib/modules/5.4.44-2-pve/kernel/drivers/net/ethernet/intel/i40e/i40e.ko
version:        2.8.20-k

(The newest Intel driver is version i40e-2.12.6/ from here: https://downloadcenter.intel.com/do...twork-Connections-Under-Linux-?product=139349 I did not install it until now)

After a login with the IPMI an a network restart via
Code:
  systemctl restart networking.service
the network Interfaces are up with an IP-Address and working.


Is this a Bug?
Or is it needed to install the newest Intel driver?

Just to be sure that you hunt down the correct problem:
AFAIK i40e is a driver only for 10G (and 40G) NICs not 1G ones

please post the output of :
Code:
lspci -nnk
ip link
cat /etc/network/interfaces

one possible cause could be that the 'predictable network names' of the nics changed, which broke the network configuration
 
Thanks for the reply

yes both point I also reflected, but I can not see a changing of the NIC names, before and after the upgrade: eno1 and eno2
and lspci show me that with this board also this driver is in use, have a look at the last 7 lines.
Our Supermicro board only have two RJ45 1GBit/s NICs, not more (and one IPMI)

I also do not understand, that the only thing I have to do is a restart of the network service, then the NICs are up and working correct
Code:
 systemctl restart networking.service

EDIT:
The only thing which we changes on this proxmox server except the upgrade is to activate the new proxmox-backup for testing it.

* does the issue persist if you boot into an older kernel?
* how many vlans do you have configured on that machine (including ones only used in guests)
* is the proxmox backup server maybe reachable over a new vlan (which you added to the node and thus maybe went over the limit of the NIC)?

Oh - and thanks for sharing the lspci output - learned that there are 1Gb NICs which use the i40e driver :)

1: we have to test it later the server is in production use
2: YES we have some vlans configured, and have changed it now to outside from proxmox to the router and vlan-Switch, so that just now neither proxmox nor one vm see vlan's
3: there is no vlan (this proxmox is the backup client, the other one (VPN - Internet) is the proxmox backup server)

maby tonight I will test a reboot without any vlan settings ... I will report
best regards,

@maxprox This is not related but I am currently having a similar issue. Apologies for talking about XCP-ng here but network interface on Intel 10G card keeps flapping and eventually loses connection. I have to reboot the host. Going to get a replacement card. I wish this is a hardware issue because if not, I don't know what to do.
