The scsi disk message "Starting disk" to signal resuming of a suspended disk is printed in both sd_resume() and sd_resume_common(), which result in this message being printed twice when resuming from e.g. autosuspend: $ echo 5000 > /sys/block/sda/device/power/autosuspend_delay_ms $ echo auto > /sys/block/sda/device/power/control [ 4962.438293] sd 0:0:0:0: [sda] Synchronizing SCSI cache [ 4962.501121] sd 0:0:0:0: [sda] Stopping disk $ echo on > /sys/block/sda/device/power/control [ 4972.805851] sd 0:0:0:0: [sda] Starting disk [ 4980.558806] sd 0:0:0:0: [sda] Starting disk Fix this double print by removing the call to sd_printk() from sd_resume() and moving the call to sd_printk() in sd_resume_common() earlier in the function, before the check using sd_do_start_stop(). Doing so, the message is printed once regardless if sd_resume_common() actually executes sd_start_stop_device() (i.e. scsi device case) or not (libsas and libata managed ATA devices case).
