Hardware: Intel NUC5CPYH, output via HDMI Display: Dell 2405FPW 1920x1200 monitor, DVI input using an HDMI-to-DVI adapter OS: Ubuntu 15.10 arch: x86_64 kernel: 4.2.0-18-generic Ran Intel Graphics Installer 1.2.1, but my understanding is that this doesn't actually change the driver used, correct? Issue: If I flick the mouse so that the pointer quickly travels from the middle to the left edge (in the lower portion of the display), I'll sometimes (1 in 4 tries) get the display to "flicker". And sometimes, instead of just flickering, it will instead turn all light grey and stay in that state. The computer is still running - any music that was playing continues to play. I can still ssh into the machine and run a shell. If I hit CTRL-ALT-F1, it appears to switch virtual consoles, as the screen changes to all black - but no text is displayed. Workarounds: Rebooting the computer fixes the problem. Suspending the computer & then waking it up also fixes the problem. dmesg: I do not see any new dmesg being output when this flickering (or the blank screen) occurs, but there are some suspect messages earlier in the log: $ dmesg | grep intel [ 1.388542] intel_idle: MWAIT substates: 0x33000020 [ 1.388547] intel_idle: v0.4 model 0x4C [ 1.388550] intel_idle: lapic_timer_reliable_states 0xffffffff [ 1.704352] fb: switching to inteldrmfb from EFI VGA [ 1.827843] fbcon: inteldrmfb (fb0) is primary device [ 1.828074] i915 0000:00:02.0: fb0: inteldrmfb frame buffer device [ 5.624276] snd_hda_intel 0000:00:1b.0: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915]) [ 6.477293] intel_rapl: Found RAPL domain package [ 6.477299] intel_rapl: Found RAPL domain core [ 360.262740] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe C FIFO underrun $ dmesg | grep ERROR [ 0.190315] acpi PNP0A08:00: _OSC failed (AE_ERROR); disabling ASPM [ 2.160410] [drm:valleyview_update_wm [i915]] *ERROR* timed out waiting for Punit DDR DVFS request [ 7.504199] [drm:valleyview_update_wm [i915]] *ERROR* timed out waiting for Punit DDR DVFS request [ 9.687075] [drm:valleyview_update_wm [i915]] *ERROR* timed out waiting for Punit DDR DVFS request [ 9.707438] [drm:valleyview_update_wm [i915]] *ERROR* timed out waiting for Punit DDR DVFS request [ 9.874539] [drm:valleyview_update_wm [i915]] *ERROR* timed out waiting for Punit DDR DVFS request [ 28.361870] [drm:valleyview_update_wm [i915]] *ERROR* timed out waiting for Punit DDR DVFS request [ 30.589794] [drm:valleyview_update_wm [i915]] *ERROR* timed out waiting for Punit DDR DVFS request [ 30.609787] [drm:valleyview_update_wm [i915]] *ERROR* timed out waiting for Punit DDR DVFS request [ 31.027400] [drm:valleyview_update_wm [i915]] *ERROR* timed out waiting for Punit DDR DVFS request [ 44.357843] [drm:valleyview_update_wm [i915]] *ERROR* timed out waiting for Punit DDR DVFS request [ 114.932016] [drm:valleyview_update_wm [i915]] *ERROR* timed out waiting for Punit DDR DVFS request [ 116.407431] [drm:valleyview_update_wm [i915]] *ERROR* timed out waiting for Punit DDR DVFS request [ 120.322528] [drm:valleyview_update_wm [i915]] *ERROR* timed out waiting for Punit DDR DVFS request [ 130.559557] [drm:valleyview_update_wm [i915]] *ERROR* timed out waiting for Punit DDR DVFS request [ 251.352101] [drm:valleyview_update_wm [i915]] *ERROR* timed out waiting for Punit DDR DVFS request [ 251.707114] [drm:valleyview_update_wm [i915]] *ERROR* timed out waiting for Punit DDR DVFS request [ 252.192934] [drm:valleyview_update_wm [i915]] *ERROR* timed out waiting for Punit DDR DVFS request [ 253.288239] [drm:valleyview_update_wm [i915]] *ERROR* timed out waiting for Punit DDR DVFS request [ 256.803667] [drm:valleyview_update_wm [i915]] *ERROR* timed out waiting for Punit DDR DVFS request [ 341.079074] [drm:valleyview_update_wm [i915]] *ERROR* timed out waiting for Punit DDR DVFS request [ 360.262740] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe C FIFO underrun
Please try v4.4-rc2 or later.
With 4.4rc2 installed, I am still able to reproduce the problem. Behavior is exactly the same.

I have exactly the same problem as described by Brad with small differences. My hardware is Intel NUC5PPYH and is connected via HDMI with no adapter. My primary OS is Ubuntu 15.10 (kernel 4.3.0-040300-generic) but I also tried Linux Mint 17.3 and Fedora 23 (both with default kernel) with the same behaviour. On Ubuntu I tried to connect to another monitor but with the same behaviour. The resolution change also makes no difference.
Created attachment 120494 [details] syslog from affected machines
I have a few of these devices (NUC5PPYH) and I can confirm it happens on all of them. It doesn't happen as much with Ubuntu 15.04 (One of my devices is running on that with Kernel 3.19.0-25-generic #26-Ubuntu SMP Fri Jul 24 21:17:31 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux). On 15.04, I just get screen flickering, but no blank/grey screen. I've tried the D-Sub port, which works absolutely fine. I've also tried Ubuntu 16.04 LTS Beta, which is affected by this issue and also the nightly drivers PPA (https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers). In Steam, I notice the game either just exits to the desktop with no error report, or it hangs with the same frame being drawn. However, on the desktop, if I move the mouse erratically from side to side (not up and down), I can reproduce this problem within seconds. I've also tried Fedora, Ubuntu Gnome and Debian, with latest drivers which all produce exactly the same problem. I'm using BIOS version 044 (which I updated to it this week), in the event it was that.
I can confirm this bug. Hardware: Intel NUC5CPYH, output via HDMI Linux desktop 3.19.0-32-generic #37~14.04.1-Ubuntu SMP Thu Oct 22 09:41:40 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux Occurs on Linux Mint and Ubuntu 15.10, when quickly moving mouse pointer in the left upper screen area.
Bug scrub ------------- Assign to me. I will check it.
I can confirm this bug also for: Intel NUC5PPYH, output via HDMI -> DVI Adapter on BenQ monitor GL2250 Linux 4.3.3-3-ARCH #1 SMP PREEMPT Wed Jan 20 08:12:23 CET 2016 x86_64 GNU/Linux Arch Linux / LXQT 0.10 / xorg-server 1.18.0-4 xf86-video-intel 1:2.99.917+519+g8229390-1 When moving the mouse cursor fast (!) to the lower left corner the monitor flickers and irregular freezes with one solid color. Repeating error message in journal: [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe C FIFO underrun
The platform is marked as Broadwell (BDW) for this bug, but when I google the NUC referred to in the various comments below, it sounds like it actually uses a Bay Trail (BYT) SoC. Maybe this is miscategorized? If this was a Broadwell issue, then I'd expect it to be fixed by http://patchwork.freedesktop.org/patch/72424/ which just went into drm-intel-nightly. But that won't have any effect on Bay Trail platforms; we may need a similar fix for those platforms.
I think it's actually Braswell. Would that be BSW? I can't find a key for deciphering the i915 platform values. http://ark.intel.com/products/codename/66094/Braswell#@All

I'll update the bug platform to reflect that and we'll check to see if a similar fix to the one I mentioned is needed for that platform. Thanks!
Hi Same issue, happens on different configurations Hardware : Intel NUC5PPYH, BIOS version 0048 Display : LG IPS236 (same on my Sony TV) OS : Ubuntu 15.10 (also on 14.04 and 15.04) Kernel : 4.2.0-27-generic Really annoying
Same issue. It only happens on HDMI port. The DP port is not affected. Hardware : ASRock Beebox N3150, BIOS v1.30 Display : Dell U2415H OS : Xubuntu 14.04.3(with xfce) Kernel : 3.19.0-51-generic #58~14.04.1-Ubuntu
Also same issue on every linux distro tested so far Hardware : Intel NUC5PPYH, BIOS version 0048 Display : Every HDMI monitor tested so far OS : Ubuntu 15.10, 15.04, OpenSuse Leap, OpenSuse Tumbleweed, Debian 8.0 NUC is a paper weight unless this is fixed.
Same problem on all of my 20 Intel NUC BOXNUC5CPYH Running Mint 17.3 X64 on HDMI Problem is gone when using VGA cable instead of HDMI. With that said i still want to use HDMI so i am interested in a fix.
Same issue. OS: Mint 17.3 X64 on HDMI Hardware: Zotac ZBOX BI323, Intel Celeron (Braswell), Intel HD Graphics
