I remember some strange case (somewhere around 2.4.18, yes I know you are running 2.6.0 whatever) where I needed to set the smp_affinity manually after boot, otherwise the second cpu would not receive any interrupts on some dual athlon system ... echo ff >/proc/irq/xx/smp_affinity did the trick, everything else was working as expected ... just a weird idea, don't blame me if it actually works ;) best, Herbert > -- > Tschoe, http://gecius.de/gpg-key.txt - Fingerprint: > Jens 1AAB 67A2 1068 77CA 6B0A 41A4 18D4 A89B 28D0 F097 > > - > 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/ - 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/
