[Bug 1658632] Re: [drm:intel_pipe_update_end [i915_bpo]] *ERROR* Atomic update failure on pipe C

 

Also, do you happen to have an external monitor, or only the built in
one?

  [drm:intel_pipe_update_end [i915_bpo]] *ERROR* Atomic update failure
  on pipe C

Bug description:
  Dell XPS 15, Ubuntu 16.04 (Ubuntu 4.4.0-59.80-generic 4.4.35), freshly
  updated. Running BTRFS and nouveau.

  The UI crashes, and put me back to the login screen after 30 seconds.

  This happens when I start softwares based on webkit (stremio, opera,
  chrome, etc). But generally only the first time. After login back and
  starting the program again, it works without crashing.

  The full dmesg error message is:

  [  113.711453] [drm:intel_pipe_update_end [i915_bpo]] *ERROR* Atomic
  update failure on pipe C (start=5158 end=5159) time 130 us, min 1073,
  max 1079, scanline start 1071, end 1080

  Repeated several times.

  I also get a:

  [  762.958586] nouveau 0000:01:00.0: priv: HUB0: 10ecc0 ffffffff
  (1d40822c)

  And a:

  [13925.500344] brcmf_cfg80211_reg_notifier: not a ISO3166 code

  but don't know if it's relevant.
