Additional reproduction results from my desktop system: Hardware:
Linux Mint 22.3 / Ubuntu 24.04 Noble base Kernel: 7.0.0-31-generic Gigabyte Z690 UD DDR4 Intel Core i7-12700K PowerColor Radeon RX 9070 XT amdgpu X11 / Cinnamon Primary monitor connected via DisplayPort Secondary monitor connected via HDMI I performed several shutdown tests. With both DisplayPort and HDMI connected: shutdown succeeded once shutdown failed once shutdown succeeded again The failure is therefore intermittent. I then physically disconnected the HDMI cable from the graphics card, leaving only the DisplayPort monitor connected. With only DisplayPort connected: 5 consecutive shutdown attempts completed successfully the system powered off completely every time The HDMI cable was disconnected from the GPU side, not merely with the monitor turned off. This strongly suggests that the HDMI connection is involved in triggering the issue on my RX 9070 XT system. Kernel 6.14.0-37-generic also shuts down correctly on the same hardware. I can see that a fix is currently planned for the linux/7.0.0-38.38 kernel. I am adding my hardware details and reproduction results anyway, in case they are useful for confirming that this issue also affects RX 9070 XT desktop systems with an Intel Z690 platform. Once 7.0.0-38.38 becomes available through the normal update channel, I can test it on this system and report whether the issue is resolved. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2163121 Title: [Regression] Laptop fails to power off completely when HDMI is connected in kernel 7.0.0-28 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2163121/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
