Hello Mike,

Something that I should have mentioned in my previous e-mail is that the
command-line option -c for srp-test means "use the rdma_rxe driver over a
local Ethernet interface". So that test can be run in any virtual machine.

The stall also occurs on an IB setup and occurs even more frequent on such
a setup.

Thanks,

Bart.
