[Kernel-packages] [Bug 1759836] Florian is dope
i started this thread the day ubuntu 18 was released, I've tried the work around. It solved my problem, so I want to thank the original solution contributor (...forgot which email it was. Read it and implemented it a while ago). but I also thank you Florian for the clear, concise, well articulated, up to date description of the work around. Specifically the line numbers and code diff. much appreciated. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bluez in Ubuntu. https://bugs.launchpad.net/bugs/1759836 Title: systemd-udevd consumes 100% of CPU Status in linux: Confirmed Status in The Ubuntu Power Consumption Project: New Status in bluez package in Ubuntu: Invalid Status in linux package in Ubuntu: Incomplete Status in systemd package in Ubuntu: Confirmed Bug description: The systemd-udevd proccess consumes 100% of a thread everytime, but i'm not noticing any difference in my computer.
