调研方向

Start by reviewing the attached nvidia-bug-report logs and the reproduction steps, especially the change to NVreg_DynamicPowerManagement and the D3cold-to-D0 resume failure. The issue does not identify source files or tests, so first trace the reported timeout in the kernel-module code and check whether the failure can be reproduced. Done means the resume failure is understood and addressed, with the reported configuration no longer producing Xid 79 or the timeout.

描述

bug

615.78.08

Please confirm this issue does not happen with the proprietary driver (of the same version). This issue tracker is only for bugs specific to the open kernel driver.

Operating System and Version

Fedora Linux 45 (Workstation Edition)

Kernel Release

Linux tong.lan 7.2.12-300.fc45.x86_64 #1 SMP PREEMPT_DYNAMIC Wed Oct 21 16:32:17 UTC 2026 x86_64 GNU/Linux

Please confirm you are running a stable release kernel (e.g. not a -rc). We do not accept bug reports for unreleased kernels.

Hardware: GPU

GPU 0: NVIDIA GeForce RTX 5070 Laptop GPU (UUID: GPU-1801f93d-3bd6-8eb8-c186-b94785017765)

Describe the bug

nvidia-bug-report.log.gz

This is a blackwell 5070, so you cannot use the proprietary drivers. So I can only test with the open drivers.

To Reproduce

Set NVreg_DynamicPowerManagement=0x02 in /etc/modprobe.d/nvidia.conf, run dracut --force.

To get things working again, set NVreg_DynamicPowerManagement=0x00
