Problem: Unreliable Hard System Freeze/Kernel Lockup on Browser
Notification (Ubuntu 25.10 / Kernel 6.17).
Log Evidence: The previous boot's journal log (journalctl -b -1) stopped
abruptly at 16:23:53 with no error or shutdown message. The /var/crash/
directory confirmed no panic report was generated, indicating a total
kernel failure before the panic handler could run.
Trigger: The freeze occurred after a chrome browser notification pop-up
(mention the browser). This is the most probable cause.
System Details: Running on the Ubuntu 25.10 development branch with
kernel 6.17.0-5-generic. This was observed in Ubuntu 25.04 as well.
