For being able to collect the following info, I’ve upgraded the system
from Oracular to Plucky (as I’m not able to install Plucky directly as
mentioned on the bug description):
The network hardware on that Power 9 bare metal system is:
$ lspci -v | grep -C 20 Ethernet

Kernel modules: i40e
and the associate kernel module is "i40e".
root@p9bm-b:~# uname -a
Linux p9bm-b 6.14.0-13-generic #13-Ubuntu SMP Wed Mar 26 21:29:12 UTC 2025

The kernel module seems to be properly included in the initramfs, in this
situation:
patricia@p9bm-b:/boot$ lsinitramfs /boot/initrd.img-6.14.0-13-generic | grep -i
i40e
usr/lib/modules/6.14.0-13-generic/kernel/drivers/net/ethernet/intel/i40e
usr/lib/modules/6.14.0-13-generic/kernel/drivers/net/ethernet/intel/i40e/i40e.ko.zst
patricia@p9bm-b:/boot$
So the req. kernel module is included in the initrd, but the module is not
loaded:
root@p9bm-b:~# lsmod | grep i40e # no output:
root@p9bm-b:~#
Now trying to insert the missing i40e module (uncompressed) leads to:
root@p9bm-b:/usr/lib/modules/6.14.0-13-generic/kernel/drivers/net/ethernet/intel/i40e#
unzstd i40e.ko.zst
i40e.ko.zst : 1296497 bytes
root@p9bm-b:/usr/lib/modules/6.14.0-13-generic/kernel/drivers/net/ethernet/intel/i40e#
ls -l
total 1560
-rw-r--r-- 1 root root 1296497 Mar 26 19:26 i40e.ko
-rw-r--r-- 1 root root 297849 Mar 26 19:26 i40e.ko.zst
It fails with “unknown symbol in module”:
root@p9bm-b:/usr/lib/modules/6.14.0-13-generic/kernel/drivers/net/ethernet/intel/i40e#
insmod ./i40e.ko
insmod: ERROR: could not insert module ./i40e.ko: Unknown symbol in module
