Bug Description

Binary package hint: gnome-system-monitor

On Freescale MX51 ARM devices, the System Monitor application's System tab displays "Unknown CPU Model" for the Processor. Screenshot attached as unknownCpuScreenshot.png.

To resolve this issue on the ARM devices, the attached 90_ARM_cpu_sysinfo.patch was added to the gnome-system-monitor package's patches. This patch is not a generic patch (it is specific to ARM) so cannot be applied to Ubuntu's gnome-system-monitor as is. However, I've attached the patch for reference.

Although the devices where the issue was encountered were running Jaunty, I have verified that the issue occurs even in Lucid's gnome-system-monitor (2.28.0-1ubuntu1) and that 90_ARM_cpu_sysinfo.patch applies cleanly to Lucid's gnome-system-monitor.

Sweet, thanks! TBH I don't fully understand the patch (need to see the
source around it), but I'll have a look at sponsoring it next week
(unless someone else beats me to it).
