Bart,
I was able to run this test case but it is not failing. On my system it passes in ~1sec.
I have several questions about your system setup.
1. Which rdma-core are you running? Out of box or the github tree?
2. Can you run ib_send_bw? Python test suite in rdma-core?
3. Where did you get the kernel bits? Which git tree? Which branch?
Thanks,
Bob Pearson

Hi Bob,
Thanks for having rebased and reposted this patch series. I have applied this series on top of commit 2169b908894d ("IB/hfi1: make hist static").
A kernel bug was triggered while running test srp/001. I have attached the kernel configuration used in my test to this email.
Thanks,
Bart.
