When I boot from an Intel X25-E SSD, it takes roughly a few seconds;
however, items such as:
$ dmesg|grep link\ down
[ 2.447030] ata4: SATA link down (SStatus 0 SControl 300)
[ 4.481288] ata5: SATA link down (SStatus 0 SControl 0)
[ 6.501288] ata6: SATA link down (SStatus 0 SControl 0)
[ 8.522038] ata7: SATA link down (SStatus 0 SControl 0)
[ 10.552288] ata8: SATA link down (SStatus 0 SControl 0)
Scanning for devices on channels that have nothing connected adds to the
boot time, is there anyway to turn off/disable scanning for certain ports
to help speed the boot process?
