This is what happens on my Ryzen7 3700X CPU installed on Gigabyte B450 Aorus Elite motherboard on 5.2.13 kernel. I got BIOS with AGESA 1.0.0.3ABB already flashed. I tried zenstates.py as well as CONFIG_RCU_NOCB_CPU=y in the kernel and passing rcu-nocbs=0-15 as a kernel parameter. None of this helps. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1690085 Title: Ryzen 1800X freeze - rcu_sched detected stalls on CPUs/tasks Status in Linux: Confirmed Status in linux package in Ubuntu: Confirmed Bug description: Hi, We aregetting various kernel crash on a pretty new config. We're using Ryzen 1800X CPU with X370 Gaming Pro Carbon MB (7A32V1) using latest BIOS available (1.52) We are running Ubuntu 17.04 (amd64), we've tried different kernel version, native one and releases from http://kernel.ubuntu.com/~kernel-ppa/mainline/ too.
