I have a problem with my Ubuntu 14.04. When I press Ctrl + Alt + F1, it always says:
login: [18.92] ata3: exception Emask 0x10 SAct 0x0 SErr 0x4040000 action 0xe frozen
[18.93] ata3: irq_stat 0x00000040, connection status changed
[21.13] ata3: SError { CommWake DevExch }
Also, it writes the 2nd and 3rd line till infinity every 2 secs. My ubuntu is not able to read the disks anymore. Please help me!!!
