It locked up with 4.4.0-040400-generic
I'll try the latest one which looks like will be 4.6.0-040600rc1

I just had an X crash with a single dvi monitor just now triggered by
logging out from an nx session
I think that one is an intel video driver bug. I have no idea if the hard
lockup is also a intel video driver bug.

Title:
  lockup when using DVI and display port with skylake

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  When using dual monitors, one connected to the dvi port, and one connected to the display port,
  and when nxclient 3.5.0-7 is running, the kernel will lock up about once a day, sometimes more often.

  after it has locked up, the mouse cursor doesn't move, caps lock doesn't toggle the keyboard light, the pc can't be pinged,
  there is nothing written in the logs about the crash.

  If nxclient isn't running, it doesn't lock up. I don't think it has
  locked up since switching to vga and dvi.

  I believe this is a skylake problem. I'm able to help test and debug
  if required and given instructions.
