Hi,

i am runnigthe latency test on i386 platform with 1 GB ram and intel pentium
4 runnig at 2.66GHz . i am getting some negative values as lat best and avg.
The results are as below

*    User space interrupt latency output*

*    == Sampling period: 10000 us*

*== Test mode: periodic user-mode task*

*== All results in microseconds*

*warming up...*

*RTT|  00:00:01  (periodic user-mode task, 10000 us period, priority 99)*

Could any figure out why these negative values are coming and reason behind
that and how i can avoid these.

is it a configuration issuse.

Thanks & regards
