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
