One line before that there should be the actual RPC error specified that we need to know what happened.

Actually this message does what it does - resends the request, so the userspace should not notice
any problems. On the other hand if any other requests aside from brw requests fail, they might not
get the resending benefit and cause userspace-visible errors.
