Since upgrading to 2.6.21 I get this message on shutdown. I know that actually the disks are spun down but the message is annoying. This apparently only happens with SATA drives.Boxes with IDE disks don't show this message. Reproducible: Always Steps to Reproduce: 1.Shutdown. 2. 3. Actual Results: The above message appears. Expected Results: No disturbing message. I came across this in /usr/src/linux/Documentation/feature-removal-schedule.txt What: libata spindown skipping and warning When: Dec 2008 Why: Some halt(8) implementations synchronize caches for and spin down libata disks because libata didn't use to spin down disk on system halt (only synchronized caches). Spin down on system halt is now implemented. sysfs node /sys/class/scsi_disk/h:c:i:l/manage_start_stop is present if spin down support is available. Because issuing spin down command to an already spun down disk makes some disks spin up just to spin down again, libata tracks device spindown status to skip the extra spindown command and warn about it. This is to give userspace tools the time to get updated and will be removed after userspace is reasonably updated. Who: Tejun Heo <htejun@gmail.com>
