Title:
  [Dell Inspiron 15 N5050] "Power Management Discrepancy" is displayed
  on wakeup

Status in “linux” package in Ubuntu:
  Confirmed
Status in “linux” source package in Precise:
  Fix Released

Bug description:
  Ever since I installed the new kernel, I am seeing this error on the
  text window when I go down for suspend:

  [xxxxxx.yyyyyy] [drm6:rp_sanitize_pm] *ERROR* Power management
  discrepancy: GEN6_RP_INTERRUPT_LIMITS, expected: 1700000, was: 1206000

  where "xxxxxx.yyyyyy" is a set of unpredictable (but increasing)
  6-digit numbers. Is there a setting I need to change in the system to
  make this error go away, or is it a bug in the new kernel?
