Yes those messages themselves are safe, but I think they may suggest the kernel got stuck for a while (somewhere, anywhere). And that would correlate with this bug.
If there were any other kernel log messages around that time then please paste them here. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1827791 Title: Dell XPS 13 9380 - Screen and input freezes / hangs temporarily Status in gnome-shell package in Ubuntu: Incomplete Bug description: Hello, I have a new 2019 Dell XPS 13 (9380). I ordered the official Ubuntu edition from Dell which came with 18.04. I then upgraded it to 18.10 for a short while, before wiping it and installing 19.04 from a fresh ISO download after that was released. This is the non-touch non-4K version (13-inch 1080p). I have the i7 model with 16GB of RAM and an NVMe SSD (so the performance should be pretty good). Sometimes when typing in Gnome Terminal, the screen just freezes for around 1 second. The cursor doesn't move, additional keypresses don't appear, and any moving content doesn't update. After the freeze stops, all the keypresses that occurred during the freeze do appear (they're not lost). Immediately after the freeze, I don't see anything in dmesg output that gives a clue. It almost feels how some old desktops did around 10-15 years ago when everything would lock up while waiting for slow HDD I/O, and then suddenly keypresses etc. would catch-up. If there is something specific I should look for immediately after a freeze in order to debug further, please let me know. Note that this happens both on battery power but also when plugged into the charger. Someone else on AskUbuntu asked this question for the same model (9380), which sounds very similar to what I'm seeing on mine (the freezing part): https://askubuntu.com/questions/1133191/ubuntu-18-04 -on-dell-xps-9380-small-freezes-and-jumping-touchpad Note that I filed https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1827790 for what I think is a separate issue related to screen flashing (as opposed to freezing). The two events do not seem to happen at the same time which is why I've filed them separately.
