I’ve been trying to solve this issue since the moment I installed Ubuntu on my machine.
Specs: Intel Core i5-10400 (10th Gen) Gigabyte H410M S2H NVIDIA GTX 1660 Super 16 GB RAM Ubuntu 24.04.3 LTS with NVIDIA 580 driver I also tried Linux Mint before Ubuntu and faced the same problem. The issue: The system freezes during shutdown, showing the final message: “reached target poweroff.target” It only happens if the system has been running for a long time (around 5+ hours, roughly estimated). The logs look completely normal — everything is unmounted correctly, and the system reaches the final message, but then it freezes. The GPU keeps running, while the mouse and keyboard become unresponsive. What I’ve tried so far: Added acpi=force Tried acpi=off Disabled TPM and Windows-related services in BIOS Disabled all GNOME extensions Updated BIOS to the latest 2025 version Currently testing with intel_iommu=off Has anyone experienced the same symptoms and managed to solve the issue? The only thing I haven’t tried yet is downgrading the kernel, which I’m trying to avoid — but it seems it might be inevitable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2031969 Title: Kernel 6.x: Suspend & Power off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2031969/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
