I cannot provke lost irqs with -f up to 2048. With -f 8192 i do get lost irq's [not amazing though]. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
