Re: GART Error 11

[Arthur Perry]

Hi Saurabh,

Thanks. It looks like you also have true GART errors as reported by hardware, on CPU0.
So our common failure mode here is actual GART errors and not something else being reported as a GART error because of erroneous kernel translation.

It's possible that we are using a device driver somewhere that is misbehaving, which is using the GART or IOMMU improperly somehow, or my guess is that is may be the actual AGP device driver used by RedHat.
ie, they may have not patched in the most recent version that may contain a lot of fixes.

Thanks for your feedback.

As of making your messages go away, I would tell you to disable the GartTableWalk in MCE, but that does not seem to work on my machine.
I'll let you know what does work without turning off Northbridge MC* entirely once I discover it.
