Hi Cyrille, Thanks for the rework, we solved this situation by moving the descriptors to an internal RAM with lower latencies, we suspected our AHB-AXI bridge + DDR Controller to delay the descriptor writes while the interrupt was handled in the meantime. But the error case was still not handled. Acked-by: Neil Armstrong <narmstr...@baylibre.com> Thanks, Neil
