Subject: hda: set_drive_speed_status: status=0x51 { DriveReady SeekComplete
 Error }

Hello,

When my system boots, I get several set_drive_speed_status errors.
(Please see attached dmesg output.)

Can someone explain what they mean? How do I get rid of them?

Is there something I need to set in the config? or something I should 
not have set?

Bonus question: is there some way to turn on DMA for hda?
