For example,
  
http://logs.test-lab.xenproject.org/osstest/logs/107573/test-amd64-amd64-qemuu-nested-intel/info.html

The L1 seems to stop producing serial output after

  [  106.376164] random: crng init done
  6.080169] random: crng init done

but it does produce a login prompt.

This passes in 3.14.  I would like to update osstest to use a recent
kernel by default, but this failure is blocking that.

Could someone investigate please ?

Let me know if you need more info, or for me to set up a repro for you
to poke at.

Thanks,
Ian.
