Hi Daniel, I need to strongly disagree with the 'Opinion' status. The issues are definitely not caused by custom modifications; in fact, the modifications were a desperate attempt to find a workaround for a broken system.
Here is the clear timeline: Ubuntu 25.04 & 25.10: Both were 100% stable on this hardware. Ubuntu 26.04 (Fresh install): The crashes started immediately. Thunderbird crashes the entire session right after launch. Remmina crashes when printing to PDF. The 'premature shutdown' explanation: When the crash occurs, the system drops me back to the LUKS decryption screen. However, the keyboard mapping is completely corrupted at that stage (it types random symbols/dots instead of the actual password). Since I cannot enter the password to resume or reboot cleanly, a hard power-off is my only option. This is what you see in the logs as a 'premature shutdown'. i3/LightDM: I only installed these after the standard GNOME/GDM3 environment proved unusable. They are a consequence of the bug, not the cause. Kernel 6.17 vs 7.x: The system is 100% stable on kernel 6.17 in both standard GNOME and i3 and unstable on kernel 7.x again in both standard GNOME and i3. The issue is strictly tied to the 7.x kernel regression. As a professional user in the middle of a high-workload season, I have limited time for testing, but I can confirm the crash is triggered by various applications, and the common denominator is always the 7.x kernel. I hope this clarifies that the 'premature shutdown' is a forced result of the initial driver/kernel failure.
