I can see both hosts talk RDMA/NVMf to each other but the initiator side can't establish a connection. Without KASAN I couldn't find a reason for it other than the following log message: rdma_rxe: qp#17 moved to error state I must admit I haven't looked up it's source yet, as my first test had KASAN enabled. > 2.

OK I'll have a look and hopefully come back with a (RFC) patch (fingers crossed).
