Comment # 71
on bug 105251
from deltasquared
I would like to pitch into this as it seems this particular problem has been plaguing me for some months now. Currently running kernel 5.2.1-arch1-1-ARCH and I will still occasionally get errors like this when running minetest (they seem to be subtly different from the others in this thread upon reading): [ 5699.136659] amdgpu 0000:0b:00.0: [gfxhub] no-retry page fault (src_id:0 ring:155 vmid:5 pasid:32770, for process minetest pid 7127 thread minetest:cs0 pid 7133) [ 5699.136662] amdgpu 0000:0b:00.0: in page starting at address 0x000080014034d000 from 27 [ 5699.136664] amdgpu 0000:0b:00.0: VM_L2_PROTECTION_FAULT_STATUS:0x00501136 [ 5704.343299] [drm:amdgpu_dm_atomic_commit_tail [amdgpu]] *ERROR* Waiting for fences timed out. [ 5709.259775] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, signaled seq=443165, emitted seq=443167 [ 5709.259860] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* Process information: process minetest pid 7127 thread minetest:cs0 pid 7133 [ 5709.259862] [drm] GPU recovery disabled. *repeat last four lines endlessly...* Relevant hardware is a ryzen 2200G (vega 8 GPU). The issue has survived swapping almost every component in my system so I think it is safe to rule out hardware brokenness in my case at least. Mercifully it seems the rest of the system survives this hence being able to capture the dmesg output, but with the gpu hard locked obviously the only recourse is to then reboot (after gathering some output for a while). I haven't yet been able to obtain an API trace from minetest when it becomes difficult. Furthermore it doesn't do so reliably - I can often play for hours, but then the crash will strike and then the issue can sometimes persist across a few reboots if I press minetest to try and load a world again fast enough. Heck idk, is it a case of the precise 3D cloud pattern in the menu background at the time? Sounds like it would be useful for me to have apitrace running in the background whenever I run it on the off chance I can catch it in the act. zzyxpaw's "vega crasher" in message #52 has reliably been able to cause GPU lock-up. Same sort of story: black window will pop up, nothing happens, and either lock-up occurs after a moment, or (interestingly) attempting to move the window in X11 will cause the lock-up immediately. If there is any more data (such as attempting to get an apitrace) that would be useful I am willing to attempt to gather it, as this issue is the only blemish on an otherwise perfectly stable system.
