My Issue When playing games(such as Black Myth: Wukong and Stellar Blade) on CachyOS, my AMD GPU suddenly crashes. The display signal is lost completely, while audio continues to play normally. After the crash and then reboot, sometimes launching a game again immediately triggers the same issue.Based on the error log: Apr 28 14:39:36 <hostname-redacted> kernel: amdgpu 0000:2d:00.0: device lost from bus! Apr 28 14:39:36 <hostname-redacted> kernel: amdgpu 0000:2d:00.0: SMU: bus error for message: TransferTableSmu2Dram(18) response:0xFFFFFFFF Apr 28 14:39:36 <hostname-redacted> kernel: in params:00000005 The GPU is no longer being recognized by the bus. I have tried downgrading packages by rolling back to a snapshot, but the issue still persists. I have come across similar issues, such as https://discuss.cachyos.org/t/screens-go-black-at-inconsistent-times-when-playing-games-amd-gpu/22438 , which manifests similarly to what I am experiencing. However, I have tried the solutions mentioned there, and none of them worked. Logs 2f25d2a Solutions I Have Tried Reinstalled CachyOS, then ran the game directly. Roll back to a snapshot version that I vaguely recall being able to play stably at some point. Disabled hardware acceleration in Firefox. Set kernel parameters to disable power saving for amdgpu, such as amdgpu.runpm=0 , etc. Tried the CachyOS-LTS kernel. Switched Proton versions, from Proton-CachyOS to GE-Proton. By The way, I tested the same scenario on Windows, and no issue occurred. My Hardware Information GPU: AMD Radeon RX 9070 XT CPU: AMD Ryzen 5 5600X Motherboard: MSI B550M PSU: 1200W (confirmed stable) Other Information As mentioned above, I tested the same scenario on Windows and did not encounter the same issue. This rules out hardware problems, such as a faulty GPU. The Steam launch parameters include: MANGOHUD=1 , PROTON_FSR4_UPGRADE=1 , game-performance .
