Hi all, I updated too my files. But, I'm still experiencing high CPU consumption by fwupd and gnome-software.

This package contains a GObject-based library to read and write AppStream XML metadata and retrieve additional data such as screenshots. . As opposed to libappstream, this library does not use an on-disk cache but reads data directly from the XML or DEP-11 YAML files. -- 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/1591868 Title: fwupd consuming 100% CPU Status in appstream-glib package in Ubuntu: Fix Released Status in appstream-glib source package in Xenial: Fix Released Status in appstream-glib source package in Yakkety: Fix Released Bug description: [Impact] * Corrupt yaml data is causing consumers of appstream data (such as gnome-software or fwupd) to get stuck in a spin and consume CPU and battery. [Test Case] * Introduce corrupt data into /var/lib/app-info/yaml/ * Execute sudo /usr/lib/x86_64-linux-gnu/fwupd/fwupd -v * Check CPU usage calms down after initialization [Regression Potential] * This patch has been backported from a newer stable release upstream. * Due to the nature of backporting, it doesn't directly apply to Ubuntu and will need some adjustments made. * Regressions would occur in gnome-software not displaying software or fwupd not running properly. [Other Info] Original bug report: fwupd process has been consuming 100% of my CPU for several days now (IBM Thinkpad x250 running fully updated 16.04). gdb backtrace below.
