Strange load average
I run Debian testing/amd64 with current kernel on an Intel Core2Duo:
$ uname -a
Linux bit 3.2.0-4-amd64 #1 SMP Debian 3.2.41-2 x86_64 GNU/Linux
When the system is idle even for long periods, the 5-minute load
average and 15-minute load average don't drop:
$ while sleep 10; do uptime; done

Is that a known kernel bug?
