--- Comment #48 from Alex Deucher <[email protected]> 2010-05-05 15:00:30 --- One of my coworkers who is also experiencing the problem bisected it down to: f3eee54276dfd1117fd94259f2b4a38388264724: commit f3eee54276dfd1117fd94259f2b4a38388264724 Author: Yinghai Lu <[email protected]> Date: Mon Dec 14 11:52:15 2009 +0900 x86: Gart: fix breakage due to IOMMU initialization cleanup This fixes the following breakage of the commit 75f1cdf1dda92cae037ec848ae63690d91913eac: - GART systems that don't AGP with broken BIOS and more than 4GB memory are forced to use swiotlb. They can allocate aperture by hand and use GART. - GART systems without GAP must disable GART on shutdown. - swiotlb usage is forced by the boot option, gart_iommu_hole_init() is not called, so we disable GART early_gart_iommu_check().
