I too have this problem: # /usr/lib/xscreensaver/hyperspace bo(0x2182ad0, 65536) is mapped (-1) can't valide it. validated 0x2182ad0 [0xF47C2000, 0xF47D2000] hyperspace: radeon_dma.c:210: radeonRefillCurrentDmaRegion: Assertion `dma_bo->bo->cref == 1' failed.
Originally saw it in ParaView, but hyperspace reproduces it more easily (in ParaView it seems to happen when I load a dataset over a certain size and try to manipulate the viewport in any way). error is much the same from ParaView: bo(0x36401e0, 65536) is mapped (-1) can't valide it. validated 0x36401e0 [0xF47C2000, 0xF47D2000] paraview-real: radeon_dma.c:210: radeonRefillCurrentDmaRegion: Assertion `dma_bo->bo->cref == 1' failed.
