xorg log
Please also attach the dmesg output from before the problem occurs, containing at least all the amdgpu and TTM initialization messages. Created attachment 139718 [details] [review] Print fpfn/lpfn values in ttm_bo_mem_space_debug Can you rebuild the ttm.ko module with this patch applied, and attach the resulting dmesg output when the problem occurs again? It might shed some more light on why we fail to evict a BO to GTT, even though there seems to be enough space there. There is no dmesg from before the problem occurs. I will try the patch!

Actually, it seems clear that this happens because 1 GB of VRAM and 3 GB of GTT are full with buffer objects. Unless this keeps happening even immediately after closing applications / logging out and back in / restarting X, this looks like a userspace issue (could be a leak somewhere). -- GitLab Migration Automatic Message -- This bug has been migrated to freedesktop.org's GitLab instance and has been closed from further activity.
