Hey,
About two-three days ago I started getting this on one of the AMD
machines I run nighly bootup test (full bootup log attached):
[Note: This is baremetal]

I haven't actually run a git bisection, but the last git commit
that does something in the gart code looks to be this one:
commit baa676fcf8d555269bd0a5a2496782beee55824d
Author: Andrzej Pietrasiewicz <andrzej.p@samsung.com>
Date: Tue Mar 27 14:28:18 2012 +0200
X86 & IA64: adapt for dma_map_ops changes
hence CC-ing on this e-email.
Was wondering if other people had seen something similar to this?

I hardly see how this commit can cause such issue. It was a pure code refactoring (attributes
parameter has been added to alloc/free functions) without any change in actual code flow. Maybe
something has been changed in core mm code or elsewhere in the driver? 'Bad page state' sounds
rather bad and might be cause by some trashing in completely unrelated code...

Doing a git bisection points it to this one:
is the first bad commit
commit 0a2b9a6ea93650b8a00f9fd5ee8fdd25671e2df6
Author: Marek Szyprowski <m.szyprowski@samsung.com>

X86: integrate CMA with DMA-mapping subsystem
This patch adds support for CMA to dma-mapping subsystem for x86
architecture that uses common pci-dma/pci-nommu implementation. This
allows to test CMA on KVM/QEMU and a lot of common x86 boxes.
