But i have an other question. I recently started to use NFS. But with the mainline kernel cpu usage is 100%, and when i look in top si shows bewteen 40 and 60% cpu usage. With your kernel si is 0%, but ksoftriqd/0 shows around 38% cpu usage and total cpu usage is around 52%. Is this normal? on my server cpu usage is 2% but it uses a intel network card. My laptop is using a wireless pcmcia card (cisco). - 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/
