The following ksysguard "Sensors" regularly show bogus values:
All "Disk Throughput" sensors
"Pages in"
"Pages out"
"Context Switches"

The bogus values are very high, like "4294958888 KBytes/s". The bogus
values always seems to be in 4.29e+09 area. (quite high!)

The bogus sensor values seems associated with heavy load and heavy I/O
activity.



Reproducible: Always
Steps to Reproduce:
1. Add("Drop") all the "Disk Throughput" sensors and the "Context Switches"
sensor from the "Load" section to a new ksysguard sheet.
2. Expose the system to heavy (I/O) load. (Like "updatedb")

Optionel steps to make it easier to catch the bogus values:
(Drop the above sensors into a ksysguard sheet and save it.)
3. Select "Multimeter" as display.
4. Right click on the sensors "Multimeter" display.
5. Choose "Properties".
6. Select "Enable Alarm" from the "Alarm for maximum value" section.
7. Type 10000 in the "Upper Limit" box.
8. Stress the system, and watch the KDE System Guard.



This problem exist in both kdebase-2.1-10.i386.rpm and the older
kdebase-2.1-8.i386.rpm.

a /usr/bin/ksysguard -v , shows this:
Qt: 2.3.0
KDE: 2.1-10
KDE System Guard: 1.1.0

The extremely large bogus values really ruins the scale on "Signal Plotter"
displays.
However, by setting a reasonable max value, this can be helped.
