Comment # 58
on bug 109955
from Mauro Gaspari
After a long time without crashes on Tumbleweed, I wanted to prepare a test setup for valve mesa built with ACO. So I installed Ubuntu Budgie 18.04 LTS with hardware enablement stack and I noticed the OS freezes are now back, even on the RadeonVII. What I noticed in the game behavior is this. This is a game running on crossover (wine) with DX11 and DXVK. I want to point out that I do alt-tab out of games to do other things, so this might be a factor to consider. But again, I do the same on my NVIDIA-GPU laptop and I never had a single freeze or fps drop. Not sure if point 2 and 3 are related, I just wanted to share my observations. 1. Game starts with excellent FPS. I can hear GPU fans spinning. 2. After a while, game loses a lot of FPS starts to become slow and sluggish, GPU seems to be no longer doing much and I can no longer hear the fans spinning. 3. After a while longer, the whole OS freezes as described in my first post. What I am going to do next: 1. Use the workaround of comment #47 and test for a few days. 2. Install Valve mesa-aco with ubuntu PPA and test (without workarounds) for a few days. I will report back when I have more details on my tests. System info: OS: Ubuntu 18.04.2 LTS x86_64 Kernel: 5.0.0-21-generic Resolution: 3440x1440 CPU: AMD Ryzen 7 2700X (16) @ 3.700G GPU: AMD Vega 20 Memory: 2650MiB / 64398MiB OpenGL version string: 4.5 (Compatibility Profile) Mesa 19.0.2
