I think next step would be to test it without out-of-tree drivers included. Please disable "evdi" driver for testing:
# Disconnect the Elgato Prompter first sudo systemctl disable --now displaylink-driver.service printf 'blacklist evdi\ninstall evdi /bin/false\n' | sudo tee /etc/modprobe.d/disable-evdi.conf sudo update-initramfs -u -k all sudo reboot After reboot, verify: lsmod | grep '^evdi\b' || echo "evdi is not loaded" Check whether you are hitting any rcu_tasks_wait_gp stalls on 7.0.0-28/29 To restore evdi after you did the test: sudo rm /etc/modprobe.d/disable-evdi.conf sudo update-initramfs -u -k all sudo systemctl enable displaylink-driver.service sudo reboot If the DisplayLink service has a different name, find it with: systemctl list-unit-files --type=service | grep -i displaylink -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2164624 Title: rcu_tasks_wait_gp stalls on 7.0.0-28/29-generic (HWE noble), absent on 6.17.0-40-generic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2164624/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
