Title:
  mount.cifs gives input/output error when connecting to port 139

Status in “cifs-utils” package in Ubuntu:
  Confirmed

Bug description:
  Mounting a network share using mount.cifs through port 139 gives an
  input/output error. I'm using port 139 because the NAS I'm connecting
  to somehow needs a netbiosname. I'm using the following command:

  /sbin/mount.cifs //IP/SHARE  MOUNTPOINT -o
  rw,guest,dir_mode=0770,file_mode=0770,uid=1000,gid=1000,port=139,netbiosname=laptop

  This command used to work: I have not changed the software or settings
  of the NAS, only updated software on the client (laptop). Although I'm
  running Lubuntu I suspect this bug is related to Ubuntu.

  I have found an identical bug on Fedora/Red Hat, with a patch that is reported to work:
  https://bugzilla.redhat.com/show_bug.cgi?id=1068862

  dmesg gives the following error, that is similar to the output given
  on the above link
