 load

Hi Toan,

We could not reproduce the issue.

We have followed the below steps.
 
        1. Booted to HP DeskElite 705 with Ubuntu 15.04.
        2. Created 1G file with urandom
        3. From another machine, repeatedly copied the 1G file back and forth with scp


With this set up and tests, we were unable to reproduce the issue. 

As we discussed offline, We also tried with your custom OS on HP DeskElite 705 and couldn't reproduce the issue.

As you suggested We also tried with 1G file provided by you but couldn't reproduce the issue.

Since We can't reproduce this issue, We are unable to proceed further.

Thank You for continuous efforts and help.

Thanks,
Satish

Toan thanks for result, so this looks to be a different problem. Sanjeev is setting up repo environment similar to yours to capture a pcie trace.
Will keep you posted.
