Hello,

I've got a new server running Proxmox VE 5.0 but since day one it crashes randomly. Any hints you guys can give me? Maybe disable SMT in BIOS? Could be a Kernel bug?

This is a Hetzner remote machine, so seeing the exact KP message is kinda hard(I have to request a KVM). The last time it was scrolling messages non-stop.

I've ran different stress tests on it, no problems. Some reboots happened when completely idle(no VMs running).

Versions:
proxmox-ve: 5.0-18 (running kernel: 4.10.17-1-pve)
pve-manager: 5.0-29 (running version: 5.0-29/6f01516)

there are different issues with the ryzen platform, those range from specific MB/Bios bugs and instabilities to stuff like https://community.amd.com/thread/215773?start=0&tstart=0 . without a concrete error message and trace it is impossible to tell what the problem might be..

Thank you kindly Fabian for your reply. I was afraid of that. I'll contact their support maybe they can help, otherwise I have to cancel the server and get Intel. Pity, I like the performance/price it has.

Is it qpossible that hetzner have not updated the BIOS (or none available) that is as new as the one I use (AGESA version 1.0.0.6a?) I have been running Ryzen for over a month now (I think) not one single crash.

This was the first thing I checked.

DMI: System manufacturer System Product Name/PRIME B350M-A, BIOS 0805 06/20/2017

The latest one from ASUS:
PRIME B350M-A BIOS 0805
Update AGESA to 1.0.0.6a

I did ask support to check the settings in BIOS, they apply some changes and I hope it works, the last crash was after 26H uptime. I will ask what they changed.

I freaking love this CPU, i don't want to switch back to Intel i7 :(

So the reply I got was "Usually we update the BIOS and disable the C-States, in most cases this helps to avoid unwanted crashes."

Bios was already up to date according to kern.log, so I guess we'll have to see if it still crashes with C-states off.

TLDR; Kernel 4.10.0 causes daily crashes on many Ryzen systems.

I thought about trying out Proxmox, but after reading about all the issues people are facing I'm having second thoughts. I ran Windows 10 on my Ryzen server since March 2017 without any issues. I switched to Fedora 26 few days ago. It is the first Linux distribution that is running stable on my system.

I have personally tried many Linux distributions on my system. Ubuntu 17.04 crashed by far the quickest and Gentoo did not completed kernel compilation so I never got to finish the install. Ubuntu 16.04.2 also could not be installed on my system.

OS that did not work:
Arch Linux (2017-03 4.10.0)
Gentoo (Early 2017-04 4.10.0)
Ubuntu 16.04.2 LTS (4.8)
Ubuntu 17.04 (4.10.0)

OS that worked without modifications:
Windows 10 Pro 64 bit
Fedora Core 26

Reports related to kernel version:
www dot reddit dot com /r/Amd/comments/62yyh4/anyone_using_ryzen_in_servers/dg6pv78/

I know there are other issues with Ryzen system, but this one does not seem to be related to issues that are officially announced (probably because it's already fixed in a newer kernel).

My system specs:
CPU: Ryzen 1700
M/B: Asus Prime 370X Pro (BIOS 0805 w/ AGESA 1.0.0.6a)

For now I going to stick with Fedora 26 with libvirt it seems to work and I don't want to run Windows on it. I am now using this machine for production so unfortunately I am unable to test.

For what it's worth, it works perfecly on my Ryzen 7 1700 (OC to 3.5) with Proxmox 5.0

I think something else is at play here, maybe it depends on the motherboard (mine is AsRock)

I really don't think that is was OP is experiencing. That bug will (as far as I can see) only occur when compiling etc.

I'm really baffled that 4.10 kernel is working for you. I have read about the kill-ryzen and save-ryzen scripts. You are correct, I don't think that issue is related to my problems (or the other reddit users' from my previous post). Today I also read a lot in the forum post that Fabian shared. That problem looks like a much bigger issue. I'm glad that it's not effecting me, touch wood.

Thanks for confirming that it's working for you. I hope you are right about it being related to the motherboard, this would mean not as many people are effected by this issue. I know that 4.11 is working for me. It's unfortunate, but it looks like I will need to wait for more people to adopt it. Stretch was released recently, so it might be a long wait. :(

The segfault issue is related to what Rhinox wrote. It's a same thing. It will ONLY happen on some early ryzen chips when compiling on all 16 cores etc... Do you compile your own kernel/packages on Proxmox? If not, don't worry about it!

First of, I seem to remember you having an asus board? I have had alot of problems with asus boards and Linux in the past (one would even start flashing a BIOS with no warning or anything.. Asus support was like "wtf." and I just got a new board, it had the same problem, 2-3 bios updates later It was fixed.. I honestly think Asus only tests for Windows and if that works, then it's good enough.

Also.. Proxmox uses Ubuntu kernel, so you will get a newer kernel (I guess) before Debian. Don't worry :) You will get whatever kernel is "stable" around the time for 5.1 (I think) maybe they will wait for 5.2.

I might compile my own kernel, but it will be a one time thing. If I run into trouble I can disable SMT/opcache/etc... If I'm stuck I can always use another machine for kernel compilation.

Yes, I have an Asus board. I think you're right again about them testing on Windows only. I'm glad to hear about Proxmox using Ubuntu kernel :)

Thanks for your time.

Yesterday I installed Proxmox 5.0 (fully updated 15 Aug 2017). The OS ran for half a day before it crashed.

I could not find any useful information in the logs. The server's screen showed some messages, one of them "watchdog: BUG: soft lockup - CPU#6 stuck for 23s!" each time with different CPU numbers and times all above 20 seconds. I tried: "/var/log# grep -ir 'soft lockup' ." but no results were found. Any idea where the logs are stored that was sent to stdout?

The soft lockup messages kept coming, I could not interact with the system using SSH or the keyboard attached to the server. Not even numlock lights would change.

Syslogs show the following around the time of the crash:
