Relevant details below, and extensive logs attached. Hardware: - NVIDIA GTX 1080 - Zorin OS 18.1 (based on Ubuntu Noble) - NVIDIA 580.178.04 Regression: - Suspend/resume works on 7.0.0-34 - Suspend/resume fails on 7.0.0-38 Observed behavior: - System enters suspend - Journal shows "PM: suspend entry (deep)" - System never resumes - Requires hard reset Testing performed: - Booted into 7.0.0-34 - suspend/resume work as-expected - Boot into 7.0.0-38 - suspend works, fails to resume - Boot into 24.04 live USB - suspend/resume work (though other, unrelated, issues are present) Regression: Yes Known-good kernel: 7.0.0-34-generic Known-bad kernel: 7.0.0-38-generic Hardware: NVIDIA GTX 1080 Tests performed: - deep suspend: fails - s2idle suspend: fails - identical hardware and userspace - previous kernel resumes correctly Result: Regression introduced between 7.0.0-34 and 7.0.0-38.
