Created attachment 1233384 [details] vmcore-dmesg.txt Description of problem: As part of upgrading from F24 to F25 I dropped back from the nv driver to the nouveau driver. I have been having random lockups since. There is no pattern that I can see to the lockups. It may happen 1/2 hour after login while I am actively using the system, or it may occur 12 hours later when the system has been idle for hours. When this happens, the cursor does still track and the system responds to SysRq commands. I enable crashdump on the system, and while I didn't get a good kernel dump I did get the dmesg output from a hung system. It points to a hard lockup in the nvkm_fantog_update function. Version-Release number of selected component (if applicable): kernel-debug-4.8.14-300.fc25.x86_64 xorg-x11-drv-nouveau-1.0.13-1.fc25.x86_64 How reproducible: Unpredictable. Steps to Reproduce: 1. Log into X 2. Wait for lockup 3. Actual results: Graphical screen locks up. Expected results: Graphics continue to function. Additional info:

This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '25'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 25 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug.
