Initial test with a fresh install of Ubuntu 20.10 Added https://gist.github.com/maxried/796d1f3101b3a03ca153fa09d3af8a11 to sign kernel images for secureboot
Updated `/etc/default/grub` to include the kernel parameters mentioned Added both ppa repos Ran `sudo apt-get install linux-firmware linux-headers-5.8.0-2026 linux- modules-5.8.0-2026-generic linux-image-unsigned-5.8.0-2026-generic` Rebooted and experienced hang, see attached image. Ran `journalctl --list-boots` and did not see the failed boot attempt listed. Added moderate blacklist mentioned above, rebooted, same results. ** Attachment added: "A screenshot of the failed boot using the 5.8.0-2026-generic kernel provided for testing" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1879633/+attachment/5429211/+files/failedboot-5.8.0-2026-generic.jpeg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1879633 Title: Killer 500s (QCA6390) WLAN/BT [17cb:1101] unavailable To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1879633/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
