 | >Description:
 | Note: this PR has already been sent out but to the wrong category 
(port-amd64), it would be better listed under the kernel part IMO. I couldn't 
find a way to remove the other report or move it in this section so I 
duplicated it.
 | 
 | Symptom:
 | On an almost "bare" system, freshly installed, the cpu usage reported by 
both TOP and PS comes near 100% for one processor on an SMP system, and never 
stops (even if completely idling).
 | 
 
 In top type 't' to show threads and see which thread is consuming all the cpu.
 Are you running raidframe and it is rebuilding?
