[GLK] all tests - dmesg-warn / dmesg-fail/fail - *ERROR* CPU pipe [AB] FIFO underrun

    • Open Issue created by Bugzilla Migration User @bugzilla-migration

    Submitted by Tomi Sarvela @tsa

    Assigned to Intel GFX Bugs mailing list

    Link to original bug (#106538)

    Description

    FIFO underruns made an appearance on Gemini Lake NUCs. Examples of tests it hits:

    https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_4182/shard-glk4/igt@kms_busy@extended-pageflip-modeset-hang-oldfb-render-b.html

    This might be residual issues from 4.17-rc5 pull, and happened only on one run on host, so we'll follow if it happens again.

      I observer similar error. Actually my computer typically freezes due to this :/ It typically happens when my computer is a sleep and some gnome nofitication appears on the lock screen. I also suspect it has something to do with my external monitory, which has from time to time hard time to wake up. Also, I suspect it started to happen with Kernel 4.17. 4.16 was almost rock stable for me.

      I am running Lenovo t470s

      I think this issue has been affecting me for a few years now but i just recently started to look into it.

      my current system is ubuntu 19.04 but this issue was present even when i was using 18.04 and 18.10 and even before that.

      os: ubuntu 19.04
      cpu: intel core i7 6700
      graphics (integrated only): hd graphics 530 (skylake gt2)

      anyway, from time to time only one of my monitors turn on. when that happens dmesg | grep i915 prints this:

when i switch to wayland, sometimes none of my monitors turn on at all. once when both turned on, i turned off one<br>
and tried to turn it back on again, but it went into energy saving mode. then `dmesg` was showing this:<br>

      I'm also affected: I'm using a T480 running Fedora 32 (kernel 5.8.4-200.fc32.x86_64) and my external monitors are regularly flickering.

      Hi Reporter, please confirm if this issue is still seen on latest kernel also.

      If yes, provide the steps to reproduce it for further debugging.
