I went over this code change repeatedly but I could not see anything
directly that would explain it. However, this patch DOES change the
way allocations are placed (while still respecting zone specifiers
like __GFP_DMA etc.) and so it's possible that they unearthed a
corruption, or a wrongly set dma mask in the drivers.

Ccing the radeon driver guys. Full quote follows.
