  Can not start (kde5) Desktop: Intel driver Failure

Status in linux package in Ubuntu:

Bug description:
  Kubuntu 15.04 start without problems to the display manager sddm. If I
  enter my password the display is blank for a second and then does
  kubuntu load forever the desktop environment.

  Dmesg shows several oopses in the intel driver:

  invalid max DP link bw val 0, using 1.62Gps


  compute-config() on unknown output!

  I think this problem occurs since the update to 3.19.0-9.

  Kernel 4.0-rc5 tested with the same problem.
