Yes. The 1053 kernel doesn't probe the NIC, i.e., the following is *missing* from the 1053 log:

We did enable HugeTLB in 1053 but I currently can't see how this could be the problem. I noticed that yours is a 2GB model but I tested (successfully) on a 4GB model. I need to try on a 2GB model. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1964114 Title: network interface is removed after latest update (pi4) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/1964114/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
