Hlo,

it still locks up.

                else if (rinfo->pm_mode & radeon_pm_d2)
                        radeon_set_suspend(rinfo, 0);

                rinfo->asleep = 0;
        } else
                radeon_engine_idle();
        goto bail;

When I comment out the rinfo->asleep = 0; line, the machine comes back. So it 
seems that rinfo struct is still corrupted somehow.
