I also confirm getting those messages: [drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR* uncleared pch fifo underrun on pch transcoder A [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun on a desktop with "Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller (rev 09)" VGA.

I can confirm identically with comment 1: Error in dmesg: [drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR* uncleared pch fifo underrun on pch transcoder A [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun VGA: Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller (rev 09) (HD 2500 in Intel i5 3550) Additional info: also with Kernel kernel-4.2.7-300.fc23.x86_64 kernel-4.2.8-300.fc23.x86_64

Fixed in 4.5 Kernel mainline. Here's my dmesg log: http://paste.fedoraproject.org/340593/45808164/

I wonder if the fix will ever get backported to the EL7 kernel.
(In reply to Dio Oktarianos Putra from comment #4) > Fixed in 4.5 Kernel mainline. What version was this fixed in? I have this problem with kernel-4.5.2-302.fc24.x86_64 xorg-x11-drv-intel-2.99.917-22.20160119.fc24.x86_64 on Fedora 24.
Does anyone know which bug out of these https://bugs.freedesktop.org/buglist.cgi?quicksearch=i915%20intel_cpu_fifo_underrun_irq_handler&list_id=579081 should I monitor for resolution?
Same happening here on my Fedora 23 with kernel 4.5.5-201.fc23.x86_64 on an Thinkpad X230 (CPU: Intel(R) Core(TM) i7-3520M CPU @ 2.90GHz) I also noted that a kernel regression test (https://git.fedorahosted.org/git/kernel-tests.git) performed on that system does not come to an end. Logs are here: https://paste.fedoraproject.org/376201/ (with SELinux disabled), and here https://paste.fedoraproject.org/376204/ (SELinux enabled). xorg-x11-drv-intel-2.99.917-19.20151206.fc23.x86_64 Here is a snip from journalctl

Updated kernel to 4.5.6. Problem persists.

This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
