Bug Description

Installing the current image `raring-preinstalled-desktop-armhf+nexus7.img` fails consistently.

Steps followed:
1. Download the *.bootimg and *.img.gz
2. Verify SHA256SUM : OK for both
3. Gunzip *.img.gz
4. fastboot erase boot and fastboot erase userdata
5. fastboot flash boot *.bootimg
6. fastboot flash userdata *.img
    sending 'userdata' (705701 KB)...

The fastboot process gets stuck here every time and top shows it is in `disk sleep`. Can't kill the process either and the device needs to be unplugged and restarted.

Problem: The size is different between manual and script install
File size reported by fastboot when installing manually: 705701 KB
File size reported by fastboot when using the installer: 692481 KB

Changed in ubuntu-nexus7:

md5sum for working raring-preinstalled-desktop-armhf+nexus7.img (version 24-Apr-2013, after unzip) is:
