Hello Christoph,

The call stack was as follows:
* __scsi_execute()
* scsi_execute_req_flags()
* scsi_vpd_inquiry()
* scsi_attach_vpd()
* scsi_probe_and_add_lun()
* __scsi_add_device()
* ata_scsi_scan_host()
* async_port_probe()
* async_run_entry_fn()
* process_one_work()
* worker_thread()
* kthread()
