https://bugzilla.kernel.org/show_bug.cgi?id=206575 Bug ID: 206575 Summary: [amdgpu] [drm] No video signal on resume from suspend, R9 380 Product: Drivers Version: 2.5 Kernel Version: 5.5 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: low Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: veox+kernel@xxxxxxx Regression: No Created attachment 287441 --> https://bugzilla.kernel.org/attachment.cgi?id=287441&action=edit dmesg output for resume-from-suspend, linux 5.5.4 OS: Arch Linux GPU: (MSI) Radeon R9 380 On `systemctl suspend` and subsequent resume, the monitors display "no signal". The machine is responsive, commands can be typed on the keyboard, SSH'ing is also possible. Somewhat unexpectedly, resume from hibernation works fine (i.e. there is signal). This started happening a few weeks ago, seemingly when `linux` v5.5.2 was installed. Was also present on v5.5.3 and v5.5.4 (current). `linux-lts` v5.4.20 does not exhibit this behaviour; it's a regression. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
