I think I figured out the issue with Trusty.  The Trusty kernel requires
the patch #10.  However, it also needs the value of
MAX_PAGE_BUFFER_COUNT bumped up to 32 from 19.

I created a Trusty test kernel with this extra patch.  It can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1495983/patched-kernel/trusty-with-extra-patch/

Once you confirm Trusty hits the same panic, can you test this kernel as
well?

  I tried with the builds from 14th and 15th of September with the same result. This bug does not affect x64 builds. 
  Tried to start the installation with different resources with no effect, kernel panic always occurs no matter the VM settings.
