Title:
  Kernel drops connection with rtl8192cu fixed driver

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have experienced a strange error a month ago when Ubuntu 14.10
  upgraded the linux kernel. rtl8192cu fixed driver stopped working. The
  error is mentioned here:
  http://askubuntu.com/questions/546195/ubuntu-14-10-rtl8192cu-
  bug/609057#609057

  The kernel 3.16.0-33-generic (maybe also some older) had this error
  and an update from 3.16.0-33-generic to 3.16.0-34-generic fixed the
  issue.

  Identical issue popped up again with a kernel update in Ubuntu 15.04
  from 3.19.0-15 to 3.19.0-16. Obviously the patches applied in
  3.16.0-34-generic shall be applied to 3.19.0-16-generic again.

  The following lines appear in the syslog all the time and the wireless
  connection is not working:
