Your kernel log appears to be flooded with debug messages making the logs unreadable, so you need to remove drm.debug. Please then reboot without drm.debug and attach a single complete system log after the next freeze:
journalctl -b-1 > prevboot.txt Just one file please. ** Package changed: ubuntu => linux (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2127687 Title: Unreliable Hard System Freeze/Kernel Lockup on Browser Notification (Ubuntu 25.10 / Kernel 6.17) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2127687/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
