Public bug reported: I believe this may be a regression (relapse of Bug #1591868 ). I upgraded to yakkety the other day without major incident and have all "updates" checked in the Software and Sources GUI. But after booting and logging in just now, I see fwupd consuming two full cores without letup.
In kern.log I see this line: fwupd[6242]: Failed to coldplug: UEFI firmware updating not supported ProblemType: Bug DistroRelease: Ubuntu 16.10 Package: fwupd 0.7.2-0ubuntu1 ProcVersionSignature: Ubuntu 4.8.0-26.28-generic 4.8.0 Uname: Linux 4.8.0-26-generic x86_64 ApportVersion: 2.20.3-0ubuntu8 Architecture: amd64 CurrentDesktop: Unity Date: Wed Oct 26 19:49:20 2016 InstallationDate: Installed on 2016-07-03 (115 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) SourcePackage: fwupd UpgradeStatus: Upgraded to yakkety on 2016-10-25 (1 days ago) ** Affects: appstream-glib (Ubuntu) Importance: Undecided Status: New ** Affects: fwupd (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug regression-update yakkety ** Also affects: appstream-glib (Ubuntu) Importance: Undecided Status: New ** Description changed: I believe this may be a regression (relapse of Bug #1591868 ).
