I don't have the hardware to test on. I was unable to reproduce it with TCP as transport and virtual machines. Unfortunatly, the customer decided to 'solve' this problem by removing the AER handling code in the SPDK stack and gave no feedback if this patch solves the problem or not. Since we can't really verify it I am not sure if you should pick the patch.
