Can you provide the branch name and commit ID for your tree with fix? I
can confirm whether it is fixed for you.

No, there are no other systems reporting the same issue. I will queue
more tests for make sure this is not a false positive.

The benchmark running slower now. This has big impact on performance,
maybe we can find some clue to optimize from the test result? The
benchmark is about file IO perf
%
to 100% on this machine with small memory. I also added proc-vmstat

found we have this feature in our test scripts already, just need to
fix a bug in script, but that is just done yesterday! Please check the

we don't collect that data during regular regression test. Is
that needed all the time? We will change our test scripts to collect
that data. But that need some time.
