Same issue happens on my Thinkpad x1 carbon 5th laptop. I just installed Ubuntu 16.04.3 alongside with Windows 10. fwupd randomly consumes 100% of the CPU but I didn't find any special err in my syslog. It just happened randomly without a signal (usually a short after booting), and I don't know how to reproduce it.
This problem can draining my laptop battery, therefore I have to disable fwupd. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to appstream-glib in Ubuntu. https://bugs.launchpad.net/bugs/1707110 Title: fwupd is consuming 100% of CPU in an upto date Ubuntu 16.04 Status in appstream-glib package in Ubuntu: Confirmed Bug description: Even though this bug is reported [https://bugs.launchpad.net/ubuntu/+source/appstream- glib/+bug/1591868] and marked as fixed, I am having the same issue on a up to date Ubuntu 16.04 system (as you can see in the attachment).
