  Test steps:
  1. Boot the machine with usb
  2. Enter the wireless password to enable the wifi connection
  3. Wait to hear the drums  and select 'Install Ubuntu' with English being the language selection
  4. Click 'Continue' with the default selections on the 'Preparing  to install ubuntu' screen( where it shows the power, available disk space and internet connectivity statu)
  5. The installation does not proceed from this point

+ Workarounds:
+ It has been reported within this bug that deleting extended partitions, or disabling swap, or mounting partitions "helps" to bypass the problem.
+ 
+ Why is this not fixed yet:
+ Well, at the moment the cause of hangs has not been determined. The best way to aid Ubuntu Installer team at fixing this bug is to provide a reproducible test case of this hang, that is is steps that one needs to perform to setup a VM / real machine that will exhibit such hang. At the moment we don't know how to trigger this bug and thus diagnose & fix it.
