Bug Description

Running Vivid with kernel 3.19 (debs from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.19-vivid/), I get the warning below in dmesg.

I can't use "ubuntu-bug linux" because I get "It appears you are currently running a mainline kernel. It would be better to report this bug upstream at http://bugzilla.kernel.org/ so that the upstream kernel developers are aware of the issue. If you'd still like to file a bug against the Ubuntu kernel, please boot with an official Ubuntu kernel and re-file.". IMHO that last advice would be a DTO (Defeating The Objective), as this message does not appear in the 3.18.

FWIW: I searched for "[drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe A (start=76355 end=76356)" and found this source code on http://lists.freedesktop.org/archives/intel-gfx/2014-February/040161.html doing the "Atomic update failure on pipe":

115 static void intel_pipe_update_end(struct intel_crtc *crtc, u32 start_vbl_count)
116 {
117 struct drm_device *dev = crtc->base.dev;
118 enum pipe pipe = crtc->pipe;
119 u32 end_vbl_count = dev->driver->get_vblank_counter(dev, pipe);
120
121 trace_i915_pipe_update_end(crtc, end_vbl_count);
122
123 local_irq_enable();
124
125 if (start_vbl_count != end_vbl_count)
126 DRM_ERROR("Atomic update failure on pipe %c (start=%u end=%u)\n",
127 pipe_name(pipe), start_vbl_count, end_vbl_count);
128 }

So because start_vbl_count != end_vbl_count I get that message in dmesg.

NB: I'm not sure the message "[drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe A (start=76355 end=76356)" has to do with the error message 12 seconds later "WARNING: CPU: 0 PID: 0 at /home/kernel/COD/linux/drivers/gpu/drm/i915/intel_display.c:9698 intel_check_page_flip+0xe6/0xf0 [i915]()"

@Sander under what circumstances are you seeing that? I see a similar message running stock Vivid on Fujitsu A544, but only if I close the lid (for suspend) immediately after booting. It does not suspend immediately, but if lid is left down it does suspend a couple of minutes later and the page_flip message is in syslog.

I don't see it if I wait a few minutes after booting and then close the lid.

I never close the lid immediately after booting, so in my case that cannot have been the cause.

So far I have not found a correlation between the intel drm flip error and things I did. Sometimes the error occurs after an hour, sometimes not for two days. Now it is even 5 days ago:

I checked if there is correlation with logging about "Lid":

I see no correlation, but I do some strange things:
"Lid closed." and "Lid opened." in that order immediately after each other (within 0.1 second). That looks untrue as I don't do that.
I really opened the Lid this morning around 07:00, but it is not in dmesg. Weird.

Same porblem on my box. I can reproduce this very often mostly using chromium.
My options for i915 driver: options i915 enable_rc6=7 enable_fbc=1 lvds_downclock=1 semaphores=1
My box is gentoo box with 4.1.2 kernel.
I had no such problems before 4.1.x kernel...

Please try v4.2-rc7 or drm-intel-nightly branch of [1], drop all i915 module parameters (such as i915.enable_rc6 i915.enable_fbc i915.lvds_downclock and i915.semaphores, they are not for regular use), add drm.debug=14, attach dmesg all the way from early boot.

I am another reporter seeing the same problem, this time in 4.2.0-rc7-00071-g0bad909 with no kernel options for drm or i915, so 4.2-rc7 does not cure it.

I do not have dmesg with drm_debug yet, will see if I can reproduce it at will (so fast I have seen it once).
