Subject: Re: radeon 0000:02:00.0: GPU lockup CP stall for more than 10000msec

Please affected people can you test if patch :
http://people.freedesktop.org/~glisse/0003-drm-radeon-fix-dma-copy-on-r6xx-r7xx-evergen-ni-si-g.patch

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,

Cheers,
Jerome
