Title:
  [Lenovo ThinkPad T520] Booting Trouble

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I have been having booting trouble with my Lenovo for months.  I have
  consistently left 12.04 and had to use other systems.  Sometimes I am
  forced to return and try to see if this issue has been fixed, it has
  not.  I have not been able to find any support for my issue, this is
  my last hope.

  Symptoms:
    1) Sometimes after grub, boots to purple screen and stays there
    2) Sometimes after grub, and purple screen, starts booting... freezes after (firewire loaded device) (however, I believe this is just the last "status" message
    3) the newest problem, after the firewire line, starts complaining with the following lines:

  [   xx.xxxxxx] ata1.00: revalidation failed (errno=-5)
  [   xx.xxxxxx] ata2.00: revalidation failed (errno=-5)

   4) Sometimes I boot successfully
   5) Sometimes I try to boot through recovery mode and sometimes it works and sometimes it doesn't.

  Notice the amount of "sometimes", this is because this bug is
  incredibly random yet I USUALLY do not boot.  Please help me out, I'll
  be glad to get whatever info you need, but I have no clue how to
  further diagnose this.

  Steps taken so far:
   -  "quiet splash" removed
   - nvidia drivers installed from nvidia's website (310)
   - nouveau driver blacklisted
