Please affected people can you test if patch : http://people.freedesktop.org/~glisse/0003-drm-radeon-fix-dma-copy-on-r6xx-r...
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.
Yes, this one also works for me. Thanks.
