This fixes the same nasty problem on my AR2425. My AR2425 will stall if it transmits for about 1~2 minutes. It sends storm of RXORN interrupts although it only transmits. I see that now lspci calls it AR5001. Jussi Kivilinna, million thanks to you. I would never think of going this direction. Luis, so I was right after all, wasn't I? It is a hardware bug that is worked around in windows driver by disabling PCIE ASPM L0S. Jussi Kivilinna, thanks again, I really mean it.
