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;
}
Any ideas on what could be causing this?
Thanks,
Paul Larson
