Problem Description:
I've been getting a somewhat random error in a few of the recent 2.5
kernels with SMP machines.  I noticed this on a 2.5.47 bk pull, but I
was also able to reproduce it on 2.5.46.  I haven't tried any earlier
kernels yet.  The LTP gettimeofday02 test sometimes fails with this
message:
gettimeofday02    0  INFO  :  checking if gettimeofday is monotonous,
takes 30s
gettimeofday02    1  FAIL  :  Time is going backwards (old
1037138184.846333 vs new 1037138184.843346!

I have not been able to reproduce this on a single processor machine
though.

Basically, all the test does is:
gettimeofday(&tv1, NULL);
while(!done) {
        gettimeofday(&tv2, NULL);
        FAIL if tv2 < tv1
        tv1 = tv2;
}

Steps to reproduce:
Run gettimeofday02 from LTP on a SMP machine.  It happens at random and may take
several tries.
