Could you please run (while running the 5.4 kernel) sudo apport-collect -p linux 1892163
That should add more information about hardware and content of logfiles. Also you could try to enable the PPA where upcoming kernel releases are made available for testing: sudo apt-add-repository ppa:canonical-kernel-team/proposed To get rid of the additional PPA later, you can run sudo apt-add-repository --remove ppa:canonical-kernel-team/proposed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1892163 Title: Major networking regression linux-image-5.4.0-42-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1892163/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
