Please affected people can you test if patch : http://people.freedesktop.org/~glisse/0003-drm-radeon-fix-dma-copy-

Fix the issue, you need to make sure you don't have the patch that disable dma on r6xx ie that line 977-978 & 1061-1062 in radeon_asic.c is : .copy = &r600_copy_dma, .copy_ring_index = R600_RING_TYPE_DMA_INDEX,
It fixes the issue for me. Thanks.
The count is actually the count, not count - 1. The real fix seems to be that r6xx requires 2 dw aligned transfers. The attached patch fixes the issue for me.

I tried this patch over kernel 3.8.0-rc2 but the GDM screen is mostly garbage. Only some text, like "Not on the list?" below the users and small icons are visible but many user names are not rendered. http://tinypic.com/r/33xihit/6 I am on Fedora 18/x86_64, Radeon HD6570.
I don't think the issue you are seeing is related to this one. Looks similar to: https://bugs.freedesktop.org/show_bug.cgi?id=55574
