Spooky behaviour with Ubuntu 24.04.x

[Ian Bruntlett]

Hi,

I've been experiencing failures with Ubuntu 24.04.2.

When experiencing these kinds of problems (listed below), what kind of
information would be useful for people interested in diagnosing the
problem? I can try a few more structured tests and hopefully help fix this
problem.

In particular, when updating from 22.04.x to 24.04.x - twice systems have
been left in a state where 24.04.x had to be re-installed from scratch. I
made copious handwritten notes.

This week, I attempted to update a Lenovo ThinkPad x201 laptop from Ubuntu
23.10 to 24.04.2 using the "Software Updater" programme. After the update,
the system would boot but would more or less immediately freeze after
login. I ran memtest86+ and it confirmed that the RAM is OK.

I thought it could be an Wayland / X Windows problem so I tried setting the
system to use "ubuntu-Xorg" when logging in but it still crashed. I tried
different memory sticks and different USB ports.

At my wit's end, I tried installing Debian 11.10 amd64. The system paused
excessively for the "Scanning the Mirror" screen so I decided to try Ubuntu
24.04.1 and it crashed.

Eventually I installed Debian 12.9.0 amd64 and it installed and ran
perfectly.

Hardware details:
Lenovo ThinkPad x201 laptop
Intel Core i7 CPU M620 at 2.67GHz
RAM 8GiB
SSD: Crucial, 512GB (or thereabouts).

I am quite happy to retry installs (complete disc) on this system in the
name of science...

TIA,


Ian
