Title:
  Dell XPS 13 - 9333 Kernel problems after update to wily

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Immediately after upgrade to wily faced several problems  on Dell XPS 13 - 9333:
  - standard boot does not complete - need to manually select upstart or recovery as home partition is LUKS encrypted using cryptsetup and standard boot does not prompt for password any more. Instead of password prompt fsck.xfs (/ is on xfs) is shown.

  - repetedly get kernel oops - USB mouse and USB keyboard have
  irregular hangs omitting mouse movement and strokes
