I think I experience the same problem as described here with my recently
built Ryzen computer. After installing a fresh Linux distribution I
started out with Linux kernel 4.19.45. The computer ran for two days
continuously, after a short pause I came back and saw it completely
froze. Screen showed the last visible image, but no input worked.
Neither ping/ssh, neither mouse or keyboard worked. Not even the num
lock LED. There were no log entries written, neither on screen or
harddisk. Last entry was some cron job, cleaning up temporary
directories. The workload was just a vim, a VNC viewer and a Firefox.
The next night, the same freeze happened. That finally got my attention
to dig deeper.
As first measure I updated the Kernel to 5.1.4. After 2 hours running,
without much load, it also froze.
I dug deeper, and as first measure I set the BIOS from "Auto" to "Typical
current Idle". Uptime is now 1 day, without any workload except a chat client.
This is
This is my System:
# CPU:
cpu family : 23
model : 1
model name : AMD Ryzen 5 1600 Six-Core Processor
stepping : 1
microcode : 0x8001137
cpu MHz : 1646.140
# Mainboard:
Gigabyte Technology Co., Ltd. B450 AORUS ELITE/B450 AORUS ELITE, BIOS F5
01/25/2019
# GPU:
NVIDIA GP107 [GeForce GTX 1050 Ti]
Driver/OpenGL: 4.6.0 NVIDIA 418.74
# OS:
Distro: Manjaro
Kernel: 5.1.4-1-MANJARO x86_64
I also see this in my bootup log:
12 times: [Firmware Bug]: ACPI MWAIT C-state 0x0 not supported by HW (0x0)
12 times: microcode: CPU0: patch_level=0x0800113
Like said, my computer is running now for 1 day without any load with the BIOS
option "Typical current Idle" set. This is so far the same "workaround" that
brodyck wrote at 2019-04-01 15:40:26 UTC. Unfortunately, or fortunately for
him, he has not wrote anything since then. That might mean, that the problems
stopped for him at that point.
I will further observe this issue with my new workstation. If you don't hear
back from me, the BIOS setting very likely worked.

Ryzen 1800X freeze - rcu_sched detected stalls on CPUs/tasks

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.
Tested kernel version:
native 17.04 kernel
4.10.15
Issues are the same, we're getting random freeze on the machine.
Here is kern.log entry when happening :

Depending on the kernel version, we've got NMI watchdog errors related to CPU
stuck (mentioning the CPU core id, which is random).
Crash is happening randomly, but in general after some hours (3-4h).
Now, we've installed kernel 4.11.0-041100-generic #201705041534 this morning
and waiting for crash...
For now, the machine is not "used", at least, it's not CPU stressed...
Thanks
