Description of problem:

Despite via https://bugzilla.redhat.com/show_bug.cgi?id=1990875 , FDI image was finally built on top of RHEL 8.6, It's still missing Network Drivers that can help discover newer hardware models e.g. Dell 7560

Version-Release number of selected component (if applicable):

foreman-discovery-image 4.1.0-10

How reproducible:

Always

Steps to Reproduce:

1. Install a Sat 6.13 and configure it for PXE-Based Discovery deployment

2. Acquire a Dell Precision 7560 laptop and connect it to the same network as the satellite

3. Boot it up in the network and try to boot into Foreman Discovery

Actual results:

After fetching the vmlinuz and initrd.img of fdi , It fails to load them properly and drops the system in dracut shell.

It's evident in the dracut shell that, Network adapters are not detected. Hence even if an rdsosreport was generated, It cannot be copied outside

Expected results:

The latest FDI images shipped with Satellite should work fine on any newer hardware.

Additional info:

The same laptop model can be built using :

• RHEL 8.4\8.5\8.6\8.7 Binary ISOs

• We can build the 8.6 or 8.7 OS on the same laptop if i use the Baremetal Network based deployment ( not discovery )

So Discovery ISO, despite being built with RHEL 8.6 kernel, seems to be missing something that RHEL 8.6 Binary DVD\Kickstart repo has \ can provide easily.

I will consider this as a regression behavior of BZ# 1990875

The end-user also confirmed that, At some point on some model, FDI had worked but only after disabling Wireless Adapter\WLAN settings in BIOS of the laptop. Or else it will get a kernel panic while loading FDI vmlinuz and initrd. So that should be fixed as well.
