Hello,
>From time to time I see an increasing temperature of the CPU of
my laptop and figured out that this has to do with a high load
of the CPU for 'interrupts' while the system itself is nearly
unused (only KDE with a few windows are up):
top(1) shows it like this:
CPU states: 0.8% user, 0.0% nice, 0.4% system, 22.9% interrupt, 76.0% idle
What could I do to figure out what's going on?
BTW: Some times ago I've asked for a small desktop gadget for showing
the CPU temperature; I wrote it like this:
$ xterm -geometry 8x1 -e '/home/guru/termal.sh'
$ cat termal.sh
#!/bin/sh
#
while true; do
clear
printf "%s %s " `sysctl -a | fgrep tempe | sed 's/^.*: //'`
sleep 15
done
I set the window properties to not having borders and it stays
there relaunched all the time by KDE again (you may see it here:
http://www.sisis.de/~guru/temp.jpg to get the idea).
