--- Comment #3 from Michel Dänzer michel@daenzer.net --- Created attachment 100907 --> https://bugs.freedesktop.org/attachment.cgi?id=100907&action=edit Hack to allow allocating larger BOs
If you have at least 1G of VRAM, this hack might help. You might also need to specify radeon.gartsize=1024 or larger on the kernel command line.
