  I can not reproduce it myself, it is a report from a different user.
  
  http://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/desktop-6th-gen-core-family-spec-update.pdf
  says there is a bug in reporting BMI support. I am not sure how exactly
  to read the document if the bug affects G4400 and if this is the real
  reason of the crash.
  
  Are you interested in working around hardware bugs?
  
We are, to some extent.

Please ask that someone else if a recent snapshot helps:

And then please report back here!
