Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. It would help us a lot if you could test it on a currently supported Ubuntu version. When you test it and it is still an issue, kindly upload the updated logs by running only once:
apport-collect <bug #>

and any other logs that are relevant for this particular issue.

Now I can log in at tty1. But, after log in, some error messages appears repeatedly to disturb me. The error messages are as follows:

[ xxxx.xxxxxx] ata4: exception Emask 0x10 SErr 0x4040000 action 0xe frozen
[ xxxx.xxxxxx] ata4: irq_stat 0x00000040, connection status changed
[ xxxx.xxxxxx] ata4: SError: { CommWake DevExch }

xxxx.xxxxxx is numbers like 9798.111376.

System: Ubuntu 14.04 LTS

Apport-collect says "Unabled identify application."

Ubuntu 14.04 (trusty) reached end-of-life on April 25,2019

Is this still an issue in a currently supported release?

In Bionic, I can open tty by pressing Ctrl+Alt+F3 (--F6). Thank you for your attention.
