Description of problem: Without any obvious cause, the screen will become severely corrupted, so much so that it's not even possible to see how many windows are open - and in one case, the corruption was followed by simple white and black vertical bars. When the screen corrupts, the machine freezes and only a hard reset works. Happens infrequently - a month between occurrences - but the hard freezes can lead to data loss. Version-Release number of selected component (if applicable): This has happened under kernels 4.19.4-200.fc28.x86_64 and 4.19.10-200.fc28.x86_64. Always using: xorg-x11-drv-nouveau-1.0.15-4.fc28.x86_64 OS is Fedora 28 using cinnamon.

Additional info: Because it causes a hard freeze, the journal is often useless, but on one occasion, I got this as the penultimate line (the last actual line being just the kernel listing all the loaded modules): kernel: WARNING: CPU: 1 PID: 0 at drivers/gpu/drm/nouveau/nvkm/subdev/mc/base.c:72 nvkm_mc_intr+0x163/0x180 [nouveau] The video corruption and this line make me believe that this is really a nouveau issue. Machine has been running Fedora for at least 5 years (being upgraded of course) and hibernates without a problem.
This message is a reminder that Fedora 28 is nearing its end of life. On 2019-May-28 Fedora will stop maintaining and issuing updates for Fedora 28. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '28'. 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 28 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 28 changed to end-of-life (EOL) status on 2019-05-28. Fedora 28 is no longer maintained, which means that it will not receive any further security or bug fix updates.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. Thank you for reporting this bug and we are sorry it could not be fixed.
