I get random crash with Ryzen 7 1800x

We recently bought a Ryzen 7 1800x to build a local server which is in our office. Since the beginning, we got random crashes which occur anytime with no specific reason. However, sometimes we are able to get some verbose log but usually, we got garbage in the syslog. I put in attachment our most recent crash with logs. Unfortunately, we are not able to reproduce the but at all. Therefore, we think it is an issue with our CPU since we observed that the cpu #8 had some issues two times. It would be great if you guys would be able to help us with that issue.

Re: I get random crash with Ryzen 7 1800x

It's important to have all system spec. RAM, GPU, MOTHERBOARD, etc etc. More details.

I've read that latest ubuntu version is 17.04. Have you tried that version?

Reading syslog i've noticed that your motherboard bios are 1201...i have the same motherboard and latest official bios is 1501. Install this one and load all default settings. I have this bios running and is fine.

In syslog there is often this error: "watchdog: BUG: soft lockup - CPU#12 stuck for 23s!" It could be a bug with that Linux specific version. If i were you, i would try Ubuntu 17.04

Also for your info, with some Ryzen CPUs there are problems with Linux: perhaps you should read this: gcc segmentation faults on Ryzen / Linux BUT before thinking that you have a Ryzen CPU with those problems, if i were you,

1)  i would update BIOS to 1501;

2) i would try latest Ubuntu version with updates;

3) in BIOS everything is at default? For example RAM?

Re: I get random crash with Ryzen 7 1800x

I've been experiencing this same issue. 

Debian Testing (kernel 4.12.0-1-amd64)

ASRock X370 Taichi

G.SKILL Ripjaws V Series 32GB (2 x 16GB) 3200 (PC4 25600) F4-3200C14D-32GVK

BIOS revision 3.00 (latest)

I've never overclocked except for testing the SoC Voltage suggestion in the GCC Segfault threat.  I had been running the RAM under the XMP profile for 3200 but have since reverted to 2400 stock speed to see if that was the issue.  I've turned off SMT as was also suggested in the Segfault thread, but that didn't help. I've reset the CMOS.  No change.

My system is lucky to make it 24 hours without locking up.  When it locks up, the fan cycles from full speed to something lower and back and the error code shows 00.

This seems to be a common problem under Linux and I've read that there may be an issue with the earliest batches of the R7 chips.  I've opened a ticket with AMD a couple of days ago, thought they have not responded to it.  I'm thinking of trying to get Newegg to accept the processor, fan, board, and memory and starting over with something that works.

Have you had any luck?

Re: I get random crash with Ryzen 7 1800x

We updated our BIOS and everything is at default in the configurations and we still have those bugs/crashes. The only thing we didn't change yet it's the Ubuntu version perhaps it will be our next step.

Re: I get random crash with Ryzen 7 1800x

There is a know bug with the AMD Ryzen 7 1800x processors and Linux.

  You should be able to open an RMA and they will ship you a different chip.

There is also another bug with the Linux Kernel which has an update also on 4.10 and 4.11

Re: I get random crash with Ryzen 7 1800x

Thank you for your reply!

My kernel is a 4.4.0+10. I don't know what means "+10". Is this version affected then?

EDIT: I did a memtest86 v7.4 memory test - after more than 6 hours I got a lot of errors for test #3 on CPU1. I'm a little uncertain:

- Is memtest86 reliable?

- Is it possible that the CPU was crashing and memtest86 shows me a false error of the RAM therefore (because the communication between CPU and RAM tored off)?

Re: I get random crash with Ryzen 7 1800x

Ok, Xenserver 7.2 is running in idle-mode with my three vm's without crashing. What I did is

- switch off "performance boost" in BIOS (leads to overclocking the CPU from 3 GHz up to 3.7 GHz)

- switch off "AMD cool'n'quiet" in BIOS (seems to be some ACPI routines)

Now the server seems to work. I put it to productive mode on sunday and up to now it looks good.

(The CPU is a Ryzen 7 1700)

Re: I get random crash with Ryzen 7 1800x

There is a Linux Kernel Bug open, see: 196683 – Random Soft Lockup on new Ryzen build

And related thread here: Re: Ryzen linux kernel bug 196683 - Random Soft Lockup

AFAICS, there are three CPU issues affecting Linux systems:

  1. SEGV under exotic load(s), see: GitHub - suaefar/ryzen-test: Tools to reproduce randomly crashing processes under load on AMD Ryzen ...
  2. streams of "watchdog: BUG: soft lockup" events being logged
  3. system freezing when idle -- nothing logged

The "SEGV" issue appears to only affect early CPUs.  AMD will replace affected CPUs.

The "soft lockup" and "system freeze" issues may be related, but are definitely not related to the "SEGV".

The "soft lockup" issue may be avoided by a combination of Kernel and Kernel-Command-Line options (see under kernel bug 196683).  My experience is that this is not sufficient to also avoid the "system freeze" issue.

The discussion under kernel bug 196683 suggests that there is a power-management related issue with the Ryzen CPUs.  Whatever the issue is, it seems that disabling the C6 (deep-sleep power-saving) state will help avoid "system freeze".  Other voodoo seems to work for some people... though there seems to be a common thread of either avoiding going idle, or otherwise preventing low voltage states (eg: http://www.silence.host/node/1) .

AMD have claimed that a late model AGESA will fix the issue.  I cannot testify to that.  It has been reported that the new BIOS options will disable C6, for some or for all cores.

Sadly, as far as I know, AMD have (to date) been unable to identify the root cause of the "soft lockup" or "system freeze" issues.
