Hello,
That error is related to your graphics card. What gfx card and what RAM
do you have?

Here's the error in the drivers code

if (rdev->family == CHIP_RS400 || rdev->family == CHIP_RS480) {
                /* FIXME: RS400 & RS480 seems to have issue with GART size
                 * if 4G of system memory (needs more testing) */
                rdev->mc.gtt_size = 32 * 1024 * 1024;
                DRM_ERROR("Forcing to 32M GART size (because of ASIC bug ?)\n");
        }

Can you let us know what hardware your system has and we can look a bit further. 

Thanks,
