Public bug reported:

Steps to reproduce the bug:
To reproduce this issue, boot a Ubuntu Live USB (created with dd or Rufus on 
Windows) on a PC containing a hard drive with at least one partition formatted 
with btrfs filesystem. At this date, it's reproducible both with Ubuntu 16.04.1 
and the Ubuntu 16.10 daily image (kernel 4.4.0-33-generic). This seems to be a 
Ubuntu specific issue so far.

Acer Aspire E15 - AMD A8-7100 + Radeon R7 M265 - 1TB HDD - 8GB RAM
