The fabrics module displays these errors. But the 28 rdma connections still get setup. I'm not sure this is what we want, but it does avoid failing the connect altogether...Bo, it's not really what we want. I think we simply need to move forward with the queue state machine, and use that to check if we have a blk-mq queue allocated for the queue. If not we can simply skip it later on. So I'd say I'll send the crash fix in blk-mq to Jens ASAP, and you'll look into the queue state machine for 4.9?
Sure.
