Default Re: [BUG REPORT] 260.19.36 64-bit Linux driver conflicts with AMD 890FX IOMMU

I'm having an issue with nvidia drivers / linux which I also resolved by disabling iommu. I run some virtualboxes on my computer and its my understanding that without IOMMU the performance degrades.

I'm using nvidia drivers: 295.20

When I was using linux 3.1.5 I could have IOMMU on in my bios. However, once I upgraded to linux 3.2.6 I had to disable it inorder to get everything working. This may be a linux 3.2.x regression, or linux 3.1.x just worked with broken nvidia drivers. I'm not sure. Is anyone else running on Linux 3.2.x with IOMMU enabled?
