1. Please describe the problem: When upgrading to kernel 5.9.8, my Logitech MX Master 2S no longer connects via bluetooth to my laptop. 2. What is the Version-Release number of the kernel: 5.9.8-100 3. Did it work previously in Fedora? If so, what kernel version did the issue *first* appear? Old kernels are available for download at https://koji.fedoraproject.org/koji/packageinfo?packageID=8 : Yes it worked before. Downgrading to the previous version, 5.8.18, fixes the problem. 4. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below: i. Boot kernel 5.9.8 ii. Pair with the bluetooth mouse from Settings > Bluetooth 5. Does this problem occur with the latest Rawhide kernel? To install the Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by ``sudo dnf update --enablerepo=rawhide kernel``: I cannot test. If I follow the above instructions I get a warning that the GPG check failed and the kernel package is not installed. 6. Are you running any modules that not shipped with directly Fedora's kernel?: VirtualBox kernel modules 7. Please attach the kernel logs. You can get the complete kernel log for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the issue occurred on a previous boot, use the journalctl ``-b`` flag. Will attach this later as I currently only have the 5.8 output. Additional info: This thread on the Arch Linux forum looks like it is about the same problem. https://bbs.archlinux.org/viewtopic.php?id=259954&p=2
