Same here. Apparently what happens is that hdapsd is triggered by lenovo's gravitational sensor, and tries to park the disk's head, in case the move is the computer falling. As the disk is an SSD, it doesn't have any mechanical part, and fails to park the head, leading to the error. Fixed by disabling/uninstalling hdapsd ( sudo apt-get remove --purge hdapsd ). But somewhat the kernel should detect it is ssd and not try to park disks, or disable hdapsd.
