FYI: SATA on x86-64

There appear to be a variety of platform problems that lead to trouble with libata (and also with the IDE driver to some extent), with the default x86-64 kernel + some buggy BIOSes + some iommu weirdness.

Here are some boot options to mix and match:
nomce, iommu=off, noapic, acpi=off

And also try using an SMP kernel (CONFIG_SMP) rather than a uniprocessor one.

You have any special place where one or several options might be useful?

I stressed the promise sata on my ASUS K8V with a Maxtor disk yesterday and it worked just fine. Under 2.4 that is. And yes, running an x86_64 kernel.
