Hi Tamas,

After comparing the two kernel-ml configuration files and finding
nothing missing, I had a sudden thought whilst considering your
statement that "the whole ieee802154 folder content is missing."

I have to ask the question:

Do you have the kernel-ml-modules-5.8.6-2.el8.elrepo.x86_64.rpm
package installed on your el8 test-system?

The -core package provides this --

$ rpm -qpl kernel-ml-core-5.8.6-2.el8.elrepo.x86_64.rpm | grep '802154'
/lib/modules/5.8.6-2.el8.elrepo.x86_64/kernel/drivers/net/ieee802154
/lib/modules/5.8.6-2.el8.elrepo.x86_64/kernel/net/ieee802154
/lib/modules/5.8.6-2.el8.elrepo.x86_64/kernel/net/ieee802154/6lowpan
/lib/modules/5.8.6-2.el8.elrepo.x86_64/kernel/net/mac802154
$

Whilst the -modules package provides this --

$ rpm -qpl kernel-ml-modules-5.8.6-2.el8.elrepo.x86_64.rpm | grep '802154'
/lib/modules/5.8.6-2.el8.elrepo.x86_64/kernel/drivers/net/ieee802154/adf7242.ko.xz
