Some architectures do not allow CPU0 to be offlined, in which case the test should return results such as what you've seen. > And why hotplug06.sar passed when CPU_TO_TESTis set to 0 and failed when > CPU_TO_TESTis set to 1? Hmm, this does seem odd. Perhaps the sar output is different on your platform. Try this: 1. Offline cpu1 2. sar -P ALL 1 0 > /tmp/log & 3. cat /tmp/log | grep -i nan sar should be outputting 'nan' for the offlined cpu. If not, then there is an issue with sar.
