kernel: hda: status error

What does this error message mean (in /var/log/messages)?

Jan 15 19:51:51 localhost kernel: hda: set_drive_speed_status: status=0x58 { DriveReady SeekComplete DataRequest }
Jan 15 19:51:51 localhost kernel: blk: queue c03cdfe0, I/O limit 4095Mb (mask 0xffffffff)

Could it have been caused by my typing "hdparm -c3d1 /dev/hda", and is it a real problem?
