It's a known kernel bug that Dell bluetooth is broken in kernels >=4.14, so sticking with the old kernel that works for now.
Kernel bluetooth bug causes bluez 97-hid2hci.rules udev rule to fail. systemd-udevd has always consumed 100% whenever a udev rule fails (could be argued that's also a bug but at least you become immediately aware there's a problem). Possibly no coincidence that the break was introduced at the same time kernel tree commits were made to btusb.c wrt. Dell 'features' being addded. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1759836 Title: systemd-udevd consumes 100% of CPU To manage notifications about this bug go to: https://bugs.launchpad.net/bluez/+bug/1759836/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
