high CPU activity for interrupts
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). matthias -- Matthias Apitz / Sisis Informationssysteme GmbH Gruenwalder Weg 28g / D-82041 Oberhaching Fon: ++49 89 / 61308-351, Fax: -399, Mobile ++49 170 4527211 http://www.sisis.de/ ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
