"""last week: Pop!_OS 22.04: kernel 6.17.9-76061709 — module BTF validation cascade boots system to emergency mode #3961

Thanks for taking a look,

Quick update — I'd already recovered before seeing this comment. The path that worked: boot Pop_OS-oldkern, run sudo apt install --reinstall linux-image-6.17.9-76061709-generic linux-modules-6.17.9-76061709-generic && sudo kernelstub, reboot. 6.17.9 came up clean. The reinstall's postinst hooks ran update-initramfs automatically; /boot/initrd.img-6.17.{4,9}-* are both freshly dated 2026-05-06 (~11:44 / 11:46), and kernelstub copied them to the EFI partition. Verified: journalctl -k -b 0 | grep -iE 'btf|failed to validate' | wc -l → 0. """

In the year 2026, on my Linux laptop (T14, Linux 6.18.26) I ran the following:

  lsmod | cut -f 1 -d ' ' | grep snd | wc -l

Having very recently (and unsuccessfully) tried to connect a printer to "real" Linux, that's not really a relevant point against ChromeOS.

In the end, after hours of frustration, my solution was to print the document from my (amusingly, Google Pixel Android) phone.

Chromebooks make a pretty nice, Linux friendly machine. They're usually cost optimized given the market they address, but that's fine if it fits your needs. Sometimes they have "weird" hardware, keyboard/mouse controllers and stuff at least wasn't always "pc standard", audio controllers seem to be commonly outside mainstream as well.

It's nice to run Linux on a machine that was built to run Linux. No silly windows key, no fighting with firmware that was built for windows first. I have a Chromebox that was a great mini desktop and the pricing was nice. My first Chromebook ran FreeBSD pretty well once it was no longer needed for ChromeOS, etc.

You have to shop carefully, you want something that's easy to put a MrChromebox firmware on and doesn't have any known issues with the OS you want to run. It's been a while since I purchased a ChromeOS device and the current state is different than it was then; I'm not sure how easy it is to find reasonable options now, but there were plenty of good options in the past. You also want to be sure that it has enough ram and storage for you needs or that those are expandable, but I think soldering ram and storage is pretty common across the range.

Crostini is kind of a joke, but I use it to remote into real Linux boxes. For me, best of both worlds.

The number of people who have "installed linux" other than ChromeOS on a Chromebook is probably in the low single digits, while the ChromeOS installed user base is in the hundreds of millions. For any given thing someone is going to try to put linux on that thing, but it is not a common use case for Chromebooks that we need to discuss.
