I met a bug recently and the kernel log: [ 330.171875] radeon 0000:03:00.0: couldn't schedule ib [ 330.175781] [drm:radeon_uvd_suspend [radeon]] *ERROR* Error destroying UVD (-22)! In radeon drivers, using UVD suspend is as follows: if (rdev->has_uvd) { uvd_v1_0_fini(rdev); radeon_uvd_suspend(rdev); } In radeon_ib_schedule function, we check the 'ring->ready' state, but in uvd_v1_0_fini funciton, we've cleared the ready state. So, just modify the suspend code flow to fix error.
