In dmesg there are a lot of these messages: radeon 0000:01:00.0: bo ffff8803df3e8400 va 0x02600000 conflict with (bo ffff8803cc35cc00 0x025FE000 0x02606000) radeon 0000:01:00.0: bo ffff8803e228c800 va 0x02600000 conflict with (bo ffff8803cc35cc00 0x025FE000 0x02606000) radeon 0000:01:00.0: bo ffff880420fbac00 va 0x02600000 conflict with (bo ffff8803cc35cc00 0x025FE000 0x02606000) radeon 0000:01:00.0: bo ffff8803bfa14c00 va 0x02600000 conflict with (bo ffff8803cc35cc00 0x025FE000 0x02606000) radeon 0000:01:00.0: bo ffff8803bfa14c00 va 0x02600000 conflict with (bo ffff8803cc35cc00 0x025FE000 0x02606000) radeon 0000:01:00.0: bo ffff8803bfa14c00 va 0x02600000 conflict with (bo ffff8803cc35cc00 0x025FE000 0x02606000)
