https://bugzilla.kernel.org/show_bug.cgi?id=112781 Bug ID: 112781 Summary: radeon: f95429e "only init fbdev if we have connectors" breaks suspend on Clevo P170EM laptop Product: Drivers Version: 2.5 Kernel Version: 4.5-rc2 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: haagch.christoph@xxxxxxxxxxxxxx Regression: No Created attachment 204201 --> https://bugzilla.kernel.org/attachment.cgi?id=204201&action=edit dmesg On a Clevo P170EM with these GPUs: 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Wimbledon XT [Radeon HD 7970M] (rev ff) With rc2 suspend stopped working. It starts to suspend, turns off the display, etc., but then it fails to actually enter the suspend state. The power stays on and after a while the radeon GPU fan starts spinning up. There's nothing in the logs relating to the problem I could find. I bisected to f95429eccc570dc45d589c327bfcfddcdc3e8228 and confirmed it with latest linux git (4.5-rc5) with this commit reverted - suspend works. Attached is a dmesg with this setup including one successful suspend and wake up. -- 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
