Created attachment 1645201 [details] dmesg, lscpu, lspci, /sys/class/drm/card0/error 1. Please describe the problem: i915 GPU hang, display freeze. Please see an attachment! 2. What is the Version-Release number of the kernel: 5.4.2-300.fc31.x86_64 3. Did it work previously in Fedora? If so, what kernel version did the issue *first* appear? Old kernels are available for download at https://koji.fedoraproject.org/koji/packageinfo?packageID=8 : I detected this problem first in 5.4.2, but GPU hang only once with 5.3.15. 4. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below: Just use my computer. 5. Does this problem occur with the latest Rawhide kernel? To install the Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by ``sudo dnf update --enablerepo=rawhide kernel``: 6. Are you running any modules that not shipped with directly Fedora's kernel?: 7. Please attach the kernel logs. You can get the complete kernel log for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the issue occurred on a previous boot, use the journalctl ``-b`` flag.
I tested with 5.4.8, but same problem. :( Latest good kernel is 5.3.18.
*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There are a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 31 kernel bugs. Fedora 31 has now been rebased to 5.5.7-200.fc31. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 32, and are still experiencing this issue, please change the version to Fedora 32. If you experience different issues, please open a new bug report for those.
5.5.7-200 solved this problem.
Thank you for letting us know.
