Stefan,
  I tried to reproduce what you did above, and the system did not come back up. Worse, there are no console messages after '[ 145.610072] Restarting system.' (this was on t1.micro). This happened 3 out of 3 times for me.

  This is the first time I've looked at those logs in depth. In both cases, user space comes up and we get to a "mounted MOUNTPOINT=/" event. That can be seen by 'cloud-init' messages. Then, something goes awry and we kernel messages like:

[ 8.923830] end_request: I/O error, dev sda1, sector 12853456
[ 8.923850] end_request: I/O error, dev sda1, sector 12853456
