AMD Ryzen 5 2400G, elementary OS 5.1.7, Ubuntu 18.04.6 LTS, System Stability Tester Version 1.5.1 generic. Testing Pi digits >= 64M with threads @ 8 will crash application, can not say for certain system crashes, as that occurred on different conditions not used on problem. Using threads @ 4 will complete task, no crash. Also during track, used 64M, 4,8 exclusively. Kernels 5.18, 5.15 will crash, kernels 5.10, 5.4 will not. Kernels were installed by Ubuntu Mainline Kernel Installer. Hopefully I can be of more help, I have not built a kernel from scratch in many of years, LFS, so for me patches to solve on my end could be issue? Steve
