I have been having such a difficult time getting a 2018 Dell Latitude 7930 to run any Linux distro stably. Maybe there is something obvious I am missing or maybe it really is dying hardware that’s the root cause of the issue.

The silly thing is I had a stable install of openSUSE Tumbleweed running for a few months but because I made some poor choices on disk partition when I installed it I was eventually backed into a corner where I had to wipe the SSD and install from scratch.

I since then have tried Tumbleweed again as well as Ubuntu, Mint, and finally Manjaro to no avail. The Debian based distros completely freeze at some point, either immediately upon login and loading the desktop or when running apt update. Tumbleweed gets a kernel panic within an hour or so, even though I changed kernel options to a previous known-good config. Now after quite a frustrating time installing Manjaro it freezes within an hour as well and the diagnostic light code indicates a CPU issue.

Strangely enough none of these issues are apparent when running from a LiveUSB, but occur on two different M.2 SATA SSDs with proper installs.

At this point I don’t really care which distro I use, as long as it doesn’t crash constantly. Does anyone have any suggestions on other things I can try?

Edit: seems to be solved with the kernel options I already mentioned. For whatever reason it didn’t work for the Tumbleweed reinstall but Manjaro has run for a couple days without crashing.

    The RAM is fine (Memtest ran 4 times without faults), and cooling seems to work well enough. Storage is ok and I used two different SSDs through this whole process and saw the same problems on both.

    I tried the previous known-good kernel options on the Manjaro install and it seems to be OK now. According to the Arch Wiki the Intel 8th Gen mobile CPUs and especially iGPUs are known to be a little problematic on Linux so the kernel options to disable some power saving options are basically non-optional. It’s weird though that it works now and didn’t on the Tumbleweed reinstall.

      I have an issue involving similar hardware, can you share the mandatory stuff for 8th gen iGPUs? read through the intel_graphics article but found no direct mention.

      did you try the i8k module?

        I linked the specific wiki page section in an edit to the main post. It’s in the troubleshooting part at the end.

        I didn’t try the i8k module but looking at a couple things it looks like the issue was more apparent around Linux kernel 4.15 from a few years ago. I also don’t have any specific complaints with temperature control. The fans only ramp up in the 70-80C range which seems to be quite reasonable.

          thanks. unfortunately, didn’t fix my problem.

          I also have a T480s with similar hardware to your Dell and it works without issues, no kernel switches necessary.
