[Bug 1480710] [NEW] partition error causes filesystem corruption

[Beat Naef]

Public bug reported:

Hello, thank you for helping me with this.

Description:	Ubuntu 14.04.2 LTS
Release:	14.04

I installed Ubuntu 14.04 via pxeboot on the same machine two times. The
root files system got corrupted both times after reboot, requiring a new
install. For both install attempts I used LVM.

The third time I installed the OS without LVM. 
Using fdisk -l, I noticed the following:
Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *        2048   968415231   484206592   83  Linux
/dev/sda2       968417278   976771071     4176897    5  Extended
Partition 2 does not start on physical sector boundary.
/dev/sda5       968417280   976771071     4176896   82  Linux swap / Solaris

I ran fdisk /dev/sda to realign partition boundaries. Partition boundary misalignment during installation may be cause for files system corruption. 
So far no problems with the partitions and filesystem.
