Austin - thank-you for your quick turnaround and summary of your investigation.
As you have shown the message loss on AIO-DX does not occur on the 4.18 kernel and only occurs on the 3.10 kernel I will mark this LP as invalid.
Please open a separate LP for the AIO-SX issue you found when using the 4.18 kernel and fix that under your new LP.
