I tried with amd64 14.04 image this time. Did ctrl-alt-fn-fn1 to see the
console while the machine is hung. Following messages might be if
interest:

INFO: rcu_sched detected stalls on CPUs/tasks: {} (detected by 0, t=15049 
jiffies, g= 1107, c=1106, q=0)
INFO: Stall ended before state dump start
BUG: soft lockup - CPU#2 stuck for 23s! [khubd:74]  --MANY OF THESE
.
.
.
INFO: task "something" blocked for more than 120 seconds. --MANY OF THESE

This keeps going on with fan at full speed.

It seems though that another user was able to boot and install. Please see link 
below.
