This is caused by missing accounting for running_req for when an internal abort command completes.  In commit 2cbbf489778e (\u0022scsi: pm8001: Use libsas internal abort support\u0022) we started to send internal abort commands as a proper sas_task. In this when we deliver a sas_task to HW the per-device running_req is incremented in pm8001_queue_command(). However it is never decremented for internal abort commnds, so decrement in pm8001_mpi_task_abort_resp().",
