When I start, shutdown and restart the live CD of Kubuntu Maverick amd64, appear on the screen repeatedly of the errors.
The error is this:
[drm:radeon_ttm_backend_bind] *ERROR* failed to bind 1772 pages at 0x00000000
[TTM] Couldn't bind backend.
radeon 0000:02:00.0: object_init failed for (7258112, 0x00000002)
[drm:radeon_gem_object_create] *ERROR* Failed to allocate GEM object (7258112, 2, 4096, -22)

1) Boot Live CD Kubuntu Maverick amd64;
2) Select the Linguage (Italian);
3) Start Kubuntu;
