Thx a log Heitor! With no mention of some new package fixing this I did not
correlate that to any patch to the kernel.
Will the be fixed in the HWE kernel as well then?

@Robert thanks for keeping this bug alive and updated!
1) More debug info required?
@Robert, reading your post

I am wondering if you asked me to provided more debug info with NVM 4.4 on my
E810 NICs? Would this

We just observed this issue on another machine of the same make and model.
Kernel log of the boot up to the crash is attached.
This machine had NO virtual machines running though. We saw side effects
such as hanging processes but were able to log in and reboot the
machine.
** Summary changed:
@Stefan Could you kindly elaborate on the "Fix Commmited"? Was there any
change to the kernel that would fix this issue? Is this fixed with 4.40
NVM from Intel?

@Robert,
first thanks a lot for pursuing this issue!
1) I certainly can provide the debugging info. May I ask if ...
a) the system in question would need to have an active LAG (LACP) for
this to be helpful? We did switch to active-backup on all our machines
due to this very issue.
b) this
FWIW, we updated our NICs to 4.30 as they were individually purchased
and not part of pre-built servers and also have this issue.
So in essence the issue also exists with the latest firmware.

1) Andre, after I switched to active-backup the issue is gone (so far).
But yeah, we are looking for a reproducer as well. It's hard to narrow
down some random issue - also likely for Intel.
2) But I just received an email from an Intel developer with a suggested
change to the driver to narrow
I ran into this issue on 22.04 LTS (using HWE kernel 6.2) on a 100G dual-port
E810 NIC.
Also with LACP only, active-backup works without issues.
To bring this more to the attention of the driver devs, I posted to the
