i40e Bug - will there be kernel updates soon?

[sigmarb]

Hi,

we just got hit by a bug with 4.15.18-10-pve Kernel and i40 10G network cards from intel.

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1779756

Problem seems to be fixed in kernel version >=4.18.

Will 4.18 be available in proxmox in the near distance?

Any help is greatly appreciated

Cheers.

Stefan

Same issue with one of my nodes

Which kernel version did you used previously? I.e., did it worked in another 4.15 release or did you use 4.13, or something else?

What's the exact symptoms/errors you observer? Please do not just say "same as linked bug report", I'd like to have your first hand information here, thanks.
We'll not update to 4.18 in PVE 5.X but we'll naturally backport the fixes once we tracked the exact ones down, I have a few candidates but I'd like to be a bit more sure about them.

A new kernel with some backported i40e fixes is available through the pvetest repository, if you want to early test them:
Either download and install it manually or configure the pvetest repository, ideally as additional repository with a reduced preference

Hi, i40e driver included in proxmox 4.15.xx.xx kernel is obsolete.

Please read thread https://forum.proxmox.com/threads/kernel-4-15-18-56-nfs-freeze-with-intel-nic-xl710.70112/
and https://yawnbox.wordpress.com/2018/10/27/updating-intels-i40e-driver-in-ubuntu-18-10/

Latest Intel XL710 driver page: https://sourceforge.net/projects/e1000/files/i40e stable/

Latest official Intel driver is 2.11.29

Please update the driver and release it.

Thank you
Paolo

Hi, i40e driver included in proxmox 4.15.xx.xx kernel is obsolete.

Upgrade to Proxmox VE 6.x which features the 5.4 kernel with a much more recent i40e driver.

Also note you cannot compare the sourceforge version with the one from the kernel, they are just two different things..

Actually an Intel Engineer recommended us also away from that driver, which is mostly for legacy distributions stuck on kernels from the 3.x or 4.4 era. https://sourceforge.net/p/e1000/bugs/620/#66b0

Note, that Proxmox VE 5.x will EOL in a few weeks anyway, so please upgrade sooner than later.

Thank you for your reply, but i wrote about i40e driver for XL710 40Gbe Nic NOT about igb Nic (1Gbit ethenet product).
These products use different drivers.

Actually i can't upgrade server until october, i'd like to solve problem with actual configuration.

Please check version about my driver.
Thank you
Paolo

Yeah, I know... But the project you and I linked are providing both and more drivers for older kernels.
Thus, the recommendation from the Intel engineers to favor running a current's Kernels built in driver holds also for i40e...

Actually i can't upgrade server until october,

Then you'll run an end-of-life version for August to October, which I heavily recommend against.

We will not switch over to an out-of-tree driver for a version which is already in maintenance mode and will go EOL in two months.
Especially as then others come and complain that the out-of-tree doesn't work with their specific HW/firmware.

Note, that you can also compile this external module yourself - if you really want it.
