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.

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.
