I freshly installed ubuntu 24.02.2 on a client. The system freezed after some time: Keyboard, mouse, network becomes unavailable. Ping and ssh are not possible. A hard reboot is required. The error is repetitive (although I do not know what triggers is)

My Hardware is: Intel i5-8400T 1.7 GHz RAM: 8GB VGA compatible controller: Intel Corporation CoffeeLake-S GT2

My software is ubuntu 24.02.2 (newest LTS) with all updates, 6.11.0-28-generic

with journalctl -b -1 -p err I see the following error messages (in the last block, the system is still running)

Anybody has an idea how to fix the freeze or how to further investigate? Help is very much appreciated!

I can't be sure, but those error messages are probably harmless. Buggy ACPI isn't uncommon, and those Gdm errors might just mean "GDM just blindly tried to launch an optional service you don't have installed".

When a system freezes, the first thing I do is determine whether it's the whole system that's frozen or just the display.

  1. Make sure the SSH daemon is running
  2. SSH in while it's not frozen to verify it works (i.e. as a control)
  3. SSH in while it is frozen

If you can SSH in while it's frozen, it might still be a driver bug, but it's not serious enough to seize up the system so the next step would be to do things like:

  1. See if sudo dmesg shows anything interesting
  2. Look at whatever the GNOME Wayland equivalent to /var/log/Xorg.0.log is (nVidia+Kubuntu 24.04.2 here. I'm still on X11)
  3. Try kill or kill -9ing your compositor or using whatever the GNOME Wayland equivalent to sudo systemctl restart sddm.service is to get a sense for how firmly the compositor is wedged. (eg. whether a userland restart without a kernel reboot can get things back.)

If you can't SSH in while it's frozen, then you've got the Linux equivalent to the Windows Blue Screen of Death and it's either dying hardware or a kernel bug (probably a driver bug).

  1. Boot https://memtest.org/ off a USB stick and confirm that it goes through a full test run without finding memory errors or freezing the system.
  2. Use a tool like smartctl as appropriate to check if any of your hard drives have logged signs of going bad. (eg. sudo smartctl -a /dev/sda will read out the logs for your first SATA hard drive. For SATA, look for things like the Offline_Uncorrectable or Reported_Uncorrect lines having a RAW_VALUE greater than 0 or entries in the SMART Self-test log structure revision number 1 not which aren't either "SMART Self-test log structure revision number 1" or interrupted... the latter being something like "you powered the system down while a self-test was running in the background".)
  3. If you get to this stage, it's probably a kernel bug (usually a driver) and the fix is certainly to upgrade (or possibly downgrade) either your kernel or, for external drivers like the nVidia drivers or VirtualBox's extensions or CDEmu's VHBA, possibly just those.

(eg. Back on kernel version 6.1.x, this Arch user found their USB WiFi dongle's driver had a system-freezing bug and, while it wasn't system-freezing, back on 22.04 LTS, I found that VirtualBox and my mother's laptop's AMD GPU drivers were giving UBSAN errors with the HWE kernel that was getting installed by default, so we downgraded to the kernel that came with 22.04.0.)
