What info is still needed? Can someone change the status at last?
Hi, so I'm back and I've got more information from my ArchLinux rig with the 3.17 stable kernel series. With the 3.17 kernel series and the intel-ucode 20140624-1 microcode loaded, I get the errors highlighted above. With the 3.17 kernel series and the intel-ucode 20140913-1 microcode loaded, I do not get the errors highlighted above. This is the microcode package for Archlinux: https://www.archlinux.org/packages/extra/any/intel-ucode/
(In reply to Claire Farron from comment #13) > With the 3.17 kernel series and the intel-ucode 20140913-1 microcode loaded, > I do not get the errors highlighted above. I have 3.17 and latest Intel microcode too, but I still randomly getting those errors...
did somebody figure out a working workaround? is there something informational which I can provide - e.g. logs?

Okay, there's not much here in terms of what actually happens. Is the error in the log all you see, or do you get black screens as well?

Another "me too". Interestingly, this just started today on a Debian testing system with an external monitor, and no kernel (or other relevant) upgrade happened recently. I can "fix" this by switching to a virtual console, and then switching back. Since it started, I had 7 of these within 2 hours.

Hi! This bug is maybe related to: https://bugs.freedesktop.org/show_bug.cgi?id=74102 # old, not fixed or undefined https://bugzilla.kernel.org/show_bug.cgi?id=95621 # new and fixed, was trigged through GDM-3.16 on Wayland Since the upgrade to GNOME 3.16 it get this error-message about a FIFO-Underrun and switching between the TTY's lead in short time to a complete hang. The patch from #95621 made the switchting between TTYs working again! But it remains "unfirm" and the error message about the FIFO-Underrun remains. Yesterday I upgraded from 3.19.3 (with patch from #95621) to 4.0.0 but it didn't changed anything. Unfirm means: Sometimes Ctrl+Alt+[1-6] doesn't work, I have to switch to another TTY first and then to the initally desired TTY. It looks like the FIFO-Message is printed before/after that happens. I can't say if this was trigged through GDM-3.16 or the changes in the development of kernel 3.19. To make this more or less a poking, I'm also affected by the following bug since 4.0.0: https://bugzilla.redhat.com/show_bug.cgi?id=1199890 Thanks Peter Hardware: Lenovo ThinkPad X220 with Intel Core I7-3xxx, HD4000 (SandyBridge) Software: Archlinux with GNOME-3.16, GDM on Wayland, GNOME-Shell on X11 Vanilla-Kernel 3.19.3, 3.19.3 with patch from #95621, 4.0.0

This bug seems to be largely solved in 4.1.0-rc2. I have 3 monitors configured. 1 is laptop internal, 1 is connected to a DisplayPort via a docking station, and 1 is connected via a DisplayPort port in my laptop. Every few hours (seems somewhat random, I cannot find any common timeframe or action), the monitor connected to the DisplayPort (I've not seen the one connected through the docking station do this), turns off, and comes back a few seconds later. Nothing crashes, no windows are moved to a different monitor, and work can resume. I see no extra information in the logs. I hope the above tale can tell someone who actually knows the driver whether or not this narrows down the possible cause. dmesg displays: [ 5238.907414] [drm:ivybridge_set_fifo_underrun_reporting [i915]] *ERROR* uncleared fifo underrun on pipe A [ 5238.907439] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun [ 5238.907461] [drm:cpt_set_fifo_underrun_reporting [i915]] *ERROR* uncleared pch fifo underrun on pch transcoder A [ 5238.907475] [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun $ xrandr --query Screen 0: minimum 8 x 8, current 5206 x 1304, maximum 32767 x 32767 LVDS1 connected primary 1366x768+0+536 (normal left inverted right x axis y axis) 309mm x 173mm 1366x768 60.1*+ 40.0 1360x768 59.8 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 DP1 connected 1920x1080+1366+0 (normal left inverted right x axis y axis) 477mm x 268mm 1920x1080 60.0*+ 1600x900 60.0 1280x1024 75.0 60.0 1152x864 75.0 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 DP2 disconnected (normal left inverted right x axis y axis) DP3 connected 1920x1080+3286+0 (normal left inverted right x axis y axis) 477mm x 268mm 1920x1080 60.0*+ 1600x900 60.0 1280x1024 75.0 60.0 1152x864 75.0 1024x768 75.1 60.0 800x600 75.0 60.3 640x480 75.0 60.0 720x400 70.1 HDMI1 disconnected (normal left inverted right x axis y axis) HDMI2 disconnected (normal left inverted right x axis y axis) HDMI3 disconnected (normal left inverted right x axis y axis) VGA1 disconnected (normal left inverted right x axis y axis) VIRTUAL1 disconnected (normal left inverted right x axis y axis)
Hello! Sorry for my bad english :) I was affected by this bug since kernel v 3.16+ running Debian (Jessie/Sid, now Stretch/sid). Once Jessie released as Stable, I did a fresh install and I was also affected by this bug. I have always did installation in Legacy mode, no in UEFI mode. Yesterday, I did a fresh Debian Jessie install (Debian 8.0.0-amd64) in UEFI mode (secure boot and legacy OPROM disabled) and the errors discussed in this bug have disappeared. No drm errors shown durring boot. Dmesg | grep -i failed = 0 drm errors. dmesg | grep drm = 0 errors. My machine: Dell Inspiron 15R Intel (R) Core(TM) i5-3337U CPU @ 1.80GHz uname -a Linux 3.16.0-4-amd64 #1 Debian 3.16.7-ckt9-3~deb8u1 (2015-04-24) x86_64 GNU/Linux With same kernel version I'm affected by this bug installing in Legacy mode, but I'm NOT affected installing in UEFI mode. So, the bug may be a uefi related ? If you need more info, tell me. I'll try to reply as soon as possible. Bye
I don't think so, I'm using UEFI on my ThinkPad all the time.
Hello, I'm affected, too. I can't say exactly when this has started, but when I plug in external monitors and want to extend to them, X crashes and I see this in dmesg: [57882.589392] [drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR* uncleared pch fifo underrun on pch transcoder A [57882.589403] [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun [57882.603123] [drm:intel_set_cpu_fifo_underrun_reporting [i915]] *ERROR* uncleared fifo underrun on pipe B [57882.603133] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe B FIFO underrun Strangely enough, mirroring works without problems.

Same here on debian testing. The problem seems to be complete randomly but somehow related to disk high load, this command here reproduce the problem for sure on my notbook. ionice -c 3 updatedb --prunepaths="/mnt/* /sys/*" Tried to compile below kernels with debian configuration and with some shot to drm options withou success. 4.0.5 4.1.1 3.19.8 dmesg shows the problem, I am using lightdm, and now with kernel 4.1.1 when it ocurrs the X server just close and return to lightdm login, that happens very fast, just a blink and I am prompted to loggin again.

With the latest 4.2 kernel on Fedora rawhide, I meet this issue intermittently. Always bugs in i915 drivers. :( I often see this during early boot, but I met this yesterday which turned my screen to black and all input devices didn't work (I tried to switch tty) under xfce. I'm using HP Z220 SFF Workstation.

Version of ucode-intel: 20140913-4.1.
Same thing happens with my laptop running a 3.19.0-26-generic , Ubuntu 15.04 after "upgrading" to this kernel version basically my laptop is useless , before that X-Server used to turn on for 1 out of 5 boots at random.. What happens now is that I can only open TTY consoles If i type my password and hit enter lightdm starts the desktop I can hear sound etc on the background and I can also take a screenshot with xwd that shows a 320x240 desktop beeing generated but the screen is black.. I have dumped debug info here : http://ammar.gr/i915_debug.txt
Booting an earlier 3.16 kernel everything works , I am also dumping the "successful" log here http://ammar.gr/i915_debug_success_Linux_3.16.0.txt also a video of the whole boot sequence that shows the TTY consoles working but the X-Server beeing dead.. http://ammar.gr/i915_laptopbootfail.mp4
I had a problem on the debian jessie 32 bit. the problem does not occur on 64-bit versions. I changed the BIOS settings efi have set Windows 8 and the rest turned off. cms support set "Never" the installer switched to installation mode efi and it's ok. Debian jessie 32 bit have a problem with that. I changed the kernel to Linux317 3.17.4 and nothing helped picked up the kernel to 4 or nothing. 32 bit I failed to install correctly.

Please try current v4.3-rc kernel.
A note for RHEL/CentOS/Scientific Linux users: if you'd like to test a v4.3-rc kernel, the latest version is available from ELRepo: http://elrepo.org/people/ajb/devel/kernel-ml/
I have this error too. HP dv7.Running most current Arch install. What is the fix?
I have the same problem on the latest kernels (but not 3.13.0). I tried 4.3-rc7 and it did not solve the problem.
I will try to use 4.3 , I have reverted to 3.16.0-38-generic #52-Ubuntu SMP Thu May 7 10:51:21 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux which works ok
finally fixed on 4.3 (on archlinux), thanks!
I am happy to also confirm that 4.3.0-040300-generic #201511020949 SMP Mon Nov 2 14:50:44 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux is working ok :) do we know what was the problem ? ( some sort of closure can be reached.. ? :P )
Seem fixed on my 4.3.0-gentoo too.
Thanks for the testing and follow-up, closing. Unfortunately I am not sure which commit fixed this. If you're interested, you can do a reverse git bisect to figure it out.
I tried it with a custom 4.3.0 on Ubuntu 14.04 and I still get: [ 16.040449] [drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR* unclea red pch fifo underrun on pch transcoder A [ 16.040478] [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun (note: this is mentioned in bug 95461, which is now marked a duplicate of this bug) This did not solve the problem for me.
Danilo, clearly this is fixed for some people (probably more accurately, some platforms/setups). We're in the process of migrating all our bug tracking to freedesktop.org, so I'd like to keep this one closed. Please either file a new bug at https://bugs.freedesktop.org/enter_bug.cgi?product=DRI&component=DRM/Intel or follow-up at https://bugs.freedesktop.org/show_bug.cgi?id=89806. That bug has links to a series claiming to fix a number of underrun issues.
