Description of problem:
When running a dual-processor under load, top sometimes reports bogus numbers. 
This appears to happen when the percentages all add up to 100% or more:

cpu00   13.4%  85.4%  1.3%  0.0%  0.0% 0.0%  3638411059903264.4%

2.  Watch top for a while

Actual Results:  Percent Idle jumps from 0 to a very large number

Expected Results:  Percent Idle stays a 0

Seems to be fixed on Fedora Core 2 Test 1, so I'll close it, and
