Hi, TL;DR. The bug was introduced after Ubuntu 21.10. It stops Ubuntu from being installed.
Details... The bug. When I boot Ubuntu 22.04 x86_64 install media (USB flash drive formatted with VENTOY) , it crashes, most often in the initial stages of the Ubuntu installer. By crash, I mean the display does not change, the keyboard is ignored, and the mouse/trackpad cursor does not move either. I have also tried installing Ubuntu 22.04 from a dedicated USB flash drive and Ubuntu also crashed. So I don't think it is a VENTOY problem. I've been doing more testing. 1. I did a full pass of memtest86+ 5.01 from the SSD in the x201 (the one with Ubuntu 18.04.6 on) with no errors. 2. Using a USB flash drive formatted with VENTOY, I booted Ubuntu 21.04, chose "Try Ubuntu" and the system ran fine for 15 minutes running top and 2 bash terminal windows (which was enough for me to consider it OK). Kernel is 5.11.0-16 14th April 2021. 3. Using a USB flash drive formatted with VENTOY, I booted Ubuntu 21.10, chose "Try Ubuntu" and the system ran fine for 15 minutes running top and 2 bash terminal windows (which was enough for me to consider it OK). Kernel is 5.13.0-19 7th Oct 2021. 4. I will be available tomorrow and some time tonight for more testing. 5. Because the system freezes quite early on, it is nearly impossible to run ubuntu-bug on behalf of Ubuntu 22.04.
