You didn't CC to me so it was impossible for me to track this bug.

Thanks, then let's debug 2.6.29.2.
http://www.kernel.org/pub/linux/kernel/people/tomo/misc/gart-debug-2.6.29.diff
As you did with 2.6.30-rc3, enable CONFIG_DMA_API_DEBUG,
CONFIG_IOMMU_DEBUG, and CONFIG_IOMMU_LEAK and don't use any kernel
boot option.
