In my case: Im running a AMD X4 System with 4 Cores. I disable core 2 via 'echo 0 > /sys/devices/system/cpu/cpu2/online' (Hotplugging via the Method described here http://www.cyberciti.biz/faq/debian-rhel-centos-redhat-suse-hotplug-cpu/) At the same time Im running a Thread that puts core 3 at full load. After disabling, the CPU Resource Monitor shows core 2 and core 3 at 0.0% even though core 3 is still running at close to 100%. After restarting the System Monitor it only shows cores 0 and 1. Core 3 is not shown, even though it is still enabled and still shows up in /proc/cpuinfo ProblemType: Bug DistroRelease: Ubuntu 10.10 Package: gnome-system-monitor 2.28.1-1ubuntu1 ProcVersionSignature: Ubuntu 2.6.35-30.54-generic 2.6.35.13 Uname: Linux 2.6.35-30-generic x86_64 NonfreeKernelModules: nvidia Architecture: amd64 Date: Thu Jul 14 15:49:23 2011 ExecutablePath: /usr/bin/gnome-system-monitor InstallationMedia: Ubuntu 10.10 "Maverick Meerkat" - Release amd64 (20101007) ProcEnviron: LANG=en_US.utf8 SHELL=/bin/bash SourcePackage: gnome-system-monitor To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-system-monitor/+bug/810498/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
