Yep, when NVIDIA and ATI entered the chipset market, who would have predicted that it would cause more 8254 and APIC related troubles? Or it would be years before it were finally fixed properly? Even worse, ATI made chipsets before AMD and Intel introduced their 64-bit CPUs, yet it was the x86-64 architecture where the attempts to fix the ATI APIC 8254 timer issues were going to. Only later when it was finally fixed properly was it backported to x86. -- 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/
