Created attachment 295869 --> https://bugzilla.kernel.org/attachment.cgi?id=295869&action=edit kernel log since resume
My system experiences a kernel panic when resuming from S3, coming from amdgpu. The GPU has to be in a specific state for this to happen. Mainly when my desktop environment turns off the screens after some inactivity, and subsequently suspends the system.
This issue only occurs with kernel versions 5.11.x. I could only reproduce this with KDE Plasma / KWin on Wayland, while testing KDE Plasma / KWin on Xorg and on Wayland (Xorg seems to work fine).
REPRODUCTION 1. Start KDE Plasma / KWin on Wayland 2. Set Screen Energy Saving "Switch off after" to a low value like 1min 3. Wait until Plasma has turned off screens 4. Suspend the system (via SSH for example) 5. Try to wake from sleep
SYSTEM INFO CPU: AMD Ryzen 9 3900X Mainboard: ASUS ROG STRIX B450-F GAMING II GPU: GIGABYTE Radeon RX VEGA 56 GAMING OC 8G
ATTACHMENTS I attached the kernel panic I could capture via ttyS0.
