I'm trying to install CentOS 7.9 via PXE on a Lenovo P620 that has a single
Aquantia 10Gb NIC
The installer (Anaconda) fails to start and the installer kernel reports:
atlantic: Bad FW version detected: 4020028
Installing the box by adding a 2nd NIC works fine and lspci reports:
01:00.0 Ethernet controller [0200]: Aquantia Corp. AQC107 NBase-T/IEEE
802.3bz Ethernet Controller [AQtion] [1d6a:07b1] (rev 02)
After a bit of googling, it looks like Lenovo PCs with this NIC use/require
'version 4' of the firmware - which is not supported by the EL 7.9 atlantic
driver (not supported until EL 8.4)
Lenovo provide Linux driver source which builds fine on EL 7.9 - and I can
insmod the new kernel module fine and it finds the NIC etc
However, I'm struggling to build an installer driver disk image and get the
CentOS 7.9 installer to use it
I've created my own 'kmod-atlantic' RPM - based on other similar ElRepo SRPMS
and it appears the installer attempts to use it - but it gives warnings like:
[ 11.087251] atlantic: loading out-of-tree module taints kernel.
[ 11.090231] atlantic: module verification failed: signature and/or
required key missing - tainting kernel
This messaging is perfectly normal - it's basically just telling you
that you've loaded a 3rd party module and that it either isn't signed
for Secure Boot or that the key it has been signed with hasn't been
imported on your system.
but doesn't seem to use the newer module?
Can anyone give me some pointers to what I need to do to get the newer kernel
module to load in the installer?
To load the module during installation, you need to create a Driver
Update Disk (DUD) from your kmod package. This takes the form of an ISO
image you can burn to CD/DVD or USB stick and pass to the installer
(anaconda).
We have written a script that we use to do the job (below) which you are
welcome to use:
https://github.com/elrepo/elrepo-scripts/blob/master/mkdd.sh
Simply run the script from the same dir that contains your kmod RPM and
SRPM. Note you should build your kmod RPM against the same kernel
version that is used on the installation media.
This video explains how to use a Driver Update Disk (DUD) when
installing CentOS/RHEL:
