Off which list? My response copied all the To and CC list from the original email: https://lore.kernel.org/lkml/002b144c-3e71-4418-3a6b-ee17c2ce6...@gmail.com/raw (except Maxime's old email which now bounces). and I have not seen a response for that email. -- Florian

No, I asked if he'd searched elsewhere to see if others are having problems, like other distros etc.

See my response to Gerhard, there are changes expected to how the network configuration should be done after: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=8fab459e69abfd04a66d76423d18ba853fced4ab > > Failing that looking for the change in the 5.6 cycle would likely be > the better bet so we can work out what broke it and report it to the > upstream driver maintainer.

If so I'm not sure what the context of the changed in 5.8 are here. If there's more changes to the driver in 5.8 dev cycle have you tried one of the Fedora rawhide 5.8 rc1 or rc2 kernel builds to see if that resolves it? Failing that looking for the change in the 5.6 cycle would likely be the better bet so we can work out what broke it and report it to the upstream driver maintainer. Have you searched to see if others are seeing a similar issue or have reported a similar issue upstream?
