I experienced this issue after I added new SSD drive to an old desktop
computer. I "fixed" this by removing the CD/DVD drive and changing SSD
SATA cable from SATA 1 to SATA 0.

Title:
  COMRESET failed (errno=-16) on Intel SSD

Status in The Linux Kernel:
  Invalid
Status in “linux” package in Ubuntu:
  Invalid

Bug description:
  On my fresh Ubuntu 12.04 on a Dell Precision (Ubuntu certified right?) with a premium
  Inted Server SSD I am forced to make the following experience.

  During boot I have to wait for 20 seconds due to the following
  scenario:

  Excerpt of dmesg | grep ata:
  [    7.718628] ata1: link is slow to respond, please be patient (ready=0)
  [   12.365148] ata1: COMRESET failed (errno=-16)
  [   17.723437] ata1: link is slow to respond, please be patient (ready=0)
  [   22.369960] ata1: COMRESET failed (errno=-16)
  [   27.728248] ata1: link is slow to respond, please be patient (ready=0)
  [   57.398789] ata1: COMRESET failed (errno=-16)
  [   57.398800] ata1: limiting SATA link speed to 1.5 Gbps
  [   57.718702] ata1: SATA link up 1.5 Gbps (SStatus 113 SControl 310)

  After that the Intel SSD is connected in limited SATA1 mode to the
  system. :-(

  The same SSD works on the same machine just fine under windows 7, 
  thus I think one can exclude hardware issues here.

  I assume that any further information is attached by the 'ubuntu-bug
  linux' command to that issue.

  
  Please help, as I would like to decrease my boot time from now 1 Minute a bit further AND most important of course I want to use a SATA mode that is capable of deliver data as fast as the super expensive drive can do it also under Ubuntu!

  Thank you for your work!
