I think the problem is that those Asus boards also don't have a HPET table. So even though NF5 has HPET the kernel doesn't know about it and the heuristic "if HPET then NF5 and timer override ok" breaks. I still suspect doing a "if (PCI ID from NF2 or NF3) ignore timer override" is probably the best solution right now. But I don't have a full list of PCI-IDs for NF2/NF3. Do you have one? Ok that might still break the NF4. I assume it never needs any timer overrides so it might be safe to include it in the PCI-IDs too. Or do you have a better proposal? -Andi - 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/ | ||||||||||||
