It feels like a cross between edge-triggered and level-triggered. I have now switched back to a pure DONE&IE (RX) or RDY&IE (TX) criterion for SLU interrupts. I find that the ROM selftest is happy but that NetBSD falls into a livelock taking an apparently-endless stream of TX interrupts. I don't yet know more. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML [email protected] / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
