Bug ID: 209535 Summary: resume fails after hibernate amdgpu Product: Drivers Version: 2.5 Kernel Version: 5.8.11 gentoo Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: s7mon@web.de Regression: No
Created attachment 292841 --> https://bugzilla.kernel.org/attachment.cgi?id=292841&action=edit dmesg with new bios (7C35v1C3)
Resume from hibernate fails with black screen and unresponsive system after image loading is completed. If my interpretation of dmesg output is correct it seems to be related to amdgpu (Radeon 5700 Navi 10 ). Ssh to machine is possible.
Suspend to memory worked so far. As well as testing levels: freezer, devices, platform, processors, core to /sys/power/pm_test with disk state according to: https://www.kernel.org/doc/Documentation/power/basic-pm-debugging.txt
When triggering hibernation (sys-power/pm-utils-1.4.1-r7) screen goes black but before power is off it seems to be restored for 1-2 seconds - not sure if that is normal or important.
I did an update to a newer bios without change of the behavior.
Harware is a MSI X570 board, Ryzen 3700X, 32G and said Radeon RX 5700. Further details in dmesg and lspci.
