3. It would be nice if I could reproduce this. I have a two-node mlx5 Infiniband
test setup, but I have done only the tiniest bit of user space IB coding, so
if you have any test programs that aren't too hard to deal with that could
possibly hit this, or be tweaked to hit it, I'd be grateful. Keeping in mind
that I'm not an advanced IB programmer. At all. :)
Clone this:
https://github.com/linux-rdma/rdma-core.git
Install all the required deps to build it (notably cython), see the README.md
$ ./build.sh
$ build/bin/run_tests.py
If you get things that far I think Leon can get a reproduction for you
Cool, it's up and running (1 failure, 3 skipped, out of 67 tests).
This is a great test suite to have running, I'll add it to my scripts. Here's the
full output in case the failure or skip cases are a problem:
