Comment 20 for bug 1475166

1) Yes there is a consistent I/O error like the one i attached in my last comment for v 3.19 and v 4.1 dmesg. This happens across multiple reboots
2)Yes, it was the I/O corruption that caused it.

Regarding what you recommended in C17 regarding installing 15.04 on SATA and stuff. I am not sure why that is different from trying the 14.10 and 3.19 kernel which is giving the error anyways. I did try creating a new ext4 partition in this 14.10 3.19 combination and running FIO on it which gave me bunch of I/O errors.
