| >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?
