 This is reproducible on my single-cpu system.

 This is however the only 5.2.1 machine I have that has this problem. I also 
 have a few SMP machines which doesn't have this problem, cpu usage 
 reporting works just fine. This system used to have a SMP-kernel since I 
 install the same kernel on all machines but after noting this problem and 
 reading this problem report I recompiled it without SMP/APIC but the 
 problem remained.
