Centos 7 install stuck on login screen - could anyone please assist in getting this error fixed?

[xenophenes]

Starting up the computer will load everything up until the background for the login screen appears, and it freezes there with no cursor or login prompt.

Ctrl-Alt-F2 to get to the command prompts reveals an error that's repeating every 3 seconds or so:

Code: Select all

exception Emask 0x0 Sact 0x8 SErr 0x0 action 0x0
irq_stat 0x40000008
failed command: READ FPDMA QUEUED

status: { DRDY ERR }
error: { UNC } 
blk_update_request: I/O error, dev sda, sector 1923858152

The lines beginning with "cmd", "res", and "blk_update_request" all change the numbers with each repeat.

This is a clean install of CentOS 7; I installed only git, docker, and golang. I also did a yum update and modified the .bashrc file to define some variables. There shouldn't be any reason for the error, but it's happened twice; the first time I reinstalled CentOS with a fresh download and did the same steps, and the same problem has occurred.

Any ideas of how to fix this or what it even is?

At an outside chance, you might have a dodgy cable to your disk but, really, it looks like it's dying. Try smartctl -a /dev/sda and see what that says.
