Sorry, I don't know how to add a tag. This tag would be "kernel-bug-
exists-upstream". And the bug is already marked as "Confirmed".

** Description changed:

  A few minutes after booting my Samsung R580 laptop, the Wi-Fi
  disconnects and it fails to reconnect until I restart the machine. This
  happens with all the 64 bit versions of Ubuntu I tried, from 14.04 to
  15.10. With the 32 bit versions, everything runs perfectly. No loss of
  connection at all, even after 48 hours in a row.
  
  Here is the output of iwconfig after loss of connexion:
  
  eth7      no wireless extensions.
  
  lo        no wireless extensions.
