Re: GART error 11

Hi Dave,

I have verified that booting the system with iommu=off (with vanilla
kernel) does seem to make the problem go away.

I apologize for not being fully up to speed with knowing what relationship
the iommu has with the gart, but I will find out.

I just wanted to post my findings.

Thanks again!
