Bug ID: 213391 Summary: AMDGPU retries page fault with some specific processes amdgpu: [gfxhub0] retry page fault until *ERROR* ring gfx timeout, but soft recovered Product: Drivers Version: 2.5 Kernel Version: Linux 5.12.9-arch-1-1 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: low Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: samy@lahfa.xyz Regression: No
Hi,
I just updated recently from mainstream Kernel 5.11.16 to 5.12.9 and I've ran into this issue, I've also updated the Mesa driver from mesa-git (21.1.0_devel.137307.f8e5f945b8f-1) to mesa-git (21.2.0_devel.140633.c04f20e7e01-1).
Current kernel parameters : /vmlinuz-linux zfs=zroot/ROOT/default rw loglevel=3 quiet radeon.si_support=0 amdgpu.si_support=1 radeon.cik_support=0 amdgpu.cik_support=1
My computer is a Thinkpad T495 laptop (AMD Ryzen 7 3700 Pro with an iGPU RX VEGA 10, 16GB DDR4 3200Mhz) the very important bit of information is that the BIOS reserves up to 2GB of DDR4 RAM for the iGPU VRAM, I currently have setup 1GB (1024MB) of RAM in my BIOS for the iGPU, I'm thinking the page fault retries could be linked to this in someways.
I think this has a higher chance of happening when my RAM memory is under heavy load and the system is swapping quite a lot too. (I have 12.3GB of Swap on a NVMe PCIe 3.0)
At present, I cannot reproduce this issue consistently yet, however it has been happening with web browsers Qutebrowser (more with Qutebrowser) and also happened only once with Chromium (made the X11 server crash and the computer completely froze, kernel was still responsive to SysReq keys hence I could get out of that tricky situation safely).
I'll be uploading both logs of the crashes I have encountered along with an lspci and other logs files that could be useful.
Kind regards,
Lahfa Samy
