https://bugzilla.kernel.org/show_bug.cgi?id=211501 Bug ID: 211501 Summary: Kernel freeze when waking monitor from blanking / DPMS (AMDGPU / DC) Product: Drivers Version: 2.5 Kernel Version: 5.10.11 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: borisovjasen@xxxxxxxxxxxxxx Regression: No Created attachment 295021 --> https://bugzilla.kernel.org/attachment.cgi?id=295021&action=edit relevant dmesg output after kernel recovered from freeze Occasional temporary kernel freeze when monitor wakes up. The freeze only happens sometimes (which makes it hard to reproduce). Most of the time, it wakes up just fine. The last time it happened, I decided to wait, rather than resetting the computer, and the system recovered after some time (less than a minute). My graphics card is a Radeon RX Vega 64. CPU is Intel i7-7700K. I have 2 connected monitors: - Gigabyte G27QC connected via DisplayPort, running at its highest mode: 2560x1440@165Hz. - Samsung SyncMaster 2243WM connected via HDMI through a DvI adapter, also at its highest mode: 1680x1050@60Hz I don't know if the issue will occur if only one of the two monitors is connected; as I said, the bug is hard to reproduce. I am using the `sway` wayland compositor. After the system recovered from the freeze, I obtained the relevant `dmesg` output. I am attaching it as `dmesg-post-freeze.txt` (with relative timestamps). I am also attaching `dmesg-boot.txt` with the kernel messages from the system booting, in case you need it for more info about my system. -- You may reply to this email to add a comment.
