All these systems (pure AMD and AMD+NVIDIA laptops) have one thing in common: the GPU gets stuck when the kernel tries to put it into deep sleep (D3cold) right before poweroff. The keyboard backlight turning on during the delay means the laptop controller is waiting for the graphics card to power down, but the card never answers.
Can you guys test adding one of these boot options in /etc/default/grub? pcie_aspm=off or amdgpu.runpm=0 Run sudo update-grub, reboot, and see if the long delay goes away. If it shuts down normally, we know for sure the 7.0 kernel is getting stuck in PCIe power management -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2165664 Title: Regression: System hangs on shutdown/reboot on kernel 7.0.0-30-generic after active workload (persists across 7.0.0-28, -29, -30) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2165664/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
