Hello, After upgrading to Linux 6.10-rc1 (Mesa is left untouched) I identified a strange bug that could cause the GPU to crash and reset while playing videos online with VA-API. The screen would first start to jitter, then flicker once or twice, but the desktop session couldn't be brought back. After a reboot I find the following messages in system logs: 10:13:05 kernel: gmc_v11_0_process_interrupt: 52 callbacks suppressed 10:13:05 kernel: amdgpu 0000:03:00.0: amdgpu: [mmhub] page fault

A crash of the program playing video (Firefox) is then triggered. It could happen any moment while playing videos. The problem is not observed in Linux 6.9, it appeared only after upgrading to 6.10-rc1. I'm new to amdgpu and I've peeked into source codes but couldn't find a call chain for the error reporting code. I've also went through drm-next commit logs, and from my understanding the updates introduced to 6.10 are many and I couldn't bisect them all. However, I'm happy to provide you with a kdump or a process dump if you request so. Please also allow me to know how I can provide you with more information. My system information: Ryzen 7840 HS, 512MB dedicated VRAM configured, Mesa 24.0.8, kernel 6.10-rc1. Hoping to hear from you soon. -- Sincerely yours, WANG Yunchen Senior, UM-SJTU Joint Institute
