[Kernel-packages] [Bug 1777863] Re: [drm:intel_wait_ddi_buf_idle [i915]] *ERROR* Timeout waiting for DDI BUF C idle bit
Hi, I also find this message in Ubuntu 22.04 recently installed. Can't see if it has any effect on my system. This here is not a laptop but a desktop ( so no docking neither lid action ). And this message does not show while booting in 20.04 on the same machine. django@ASGARD:~$ sudo dmesg | grep i915 [6.806751] i915 :00:02.0: vgaarb: deactivate vga console [6.812971] i915 :00:02.0: vgaarb: changed VGA decodes: olddecodes=io+mem,decodes=io+mem:owns=io+mem [6.846945] [drm] Initialized i915 1.6.0 20201103 for :00:02.0 on minor 0 [6.874018] fbcon: i915drmfb (fb0) is primary device [6.891951] i915 :00:02.0: [drm] *ERROR* Timeout waiting for DDI BUF B to get idle [6.929012] i915 :00:02.0: [drm] fb0: i915drmfb frame buffer device [6.975375] snd_hda_intel :00:03.0: bound :00:02.0 (ops i915_audio_component_bind_ops [i915]) django@ASGARD:~$ django@ASGARD:~$ echo ; lsb_release -dcs; uname -srpi; echo $DESKTOP_SESSION sous $XDG_SESSION_TYPE parmi :; ls /usr/share/xsessions Ubuntu 22.04 LTS jammy Linux 5.15.0-40-generic x86_64 x86_64 ubuntu-xorg sous x11 parmi : ubuntu.desktop ubuntu-xorg.desktop django@ASGARD:~$ -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1777863 Title: [drm:intel_wait_ddi_buf_idle [i915]] *ERROR* Timeout waiting for DDI BUF C idle bit Status in linux package in Ubuntu: Confirmed Bug description: System reboot.

I have this exact same issue. I have connected two displays (RGB and HDMI cables) I've updated from Ubuntu 18.04 to 18.10. Everything was working correctly in 18.04. Steps to reproduce: Case 1: 1. Start docked laptop with displays connected in the docking station 2. Undock laptop 3. Redock laptop -> Freeze/black screen Case 2: 1. Start docked laptop without displays connected in the docking station 2. Undock laptop 3. Redock laptop 4.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.17 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
