Just finished building the latest git for my dual-opteron box(ASUS K8N-DL with 6GB Ram). No new issues noted, works about as well as 2.6.12 for me. ASUS still has not addressed their ACPI Table and I am doubtful that they ever will.
In order to boot any kernel, I am disabling ACPI in the BIOS. If I enable ACPI, I now get a lock-up referencing the fact the machine has 6GB of RAM and no IOMMU. I have attached the "dmesg" of the boot with ACPI disabled if you folks are interested. Sean P.S. ASUS TechSupport is only slightly better than Belkin(Their KVM's suck) TechSupport!
