Can someone tell me what is going on? in the ol' BP6 times (dual Celeron) APIC errors where reported (by certain 2.4.x kernels, previous versions simply ignored them) when an error occured while the CPUs where communicating ... as far as I understood, the communication between APIC and CPU is checksummed (a very simple checksum, like a parity) and if this checksum is invalid, the action is restarted, so this okay, because an error was avoided, but because the checksum is so simple (IIRC only two bits), chances are good that some faulty communication will go undetected ... please, I'm no expert on Athlon APIC or such stuff, so this could be total bullshit, but maybe some APIC expert will comment on that ;) best, Herbert > Info about my machine's hardware: > http://www.enodev.com/info.html > - > 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/
