Machines with AMD CPUs Ryzen 5 1600 and Ryzen 7 1700 crash regularly

I have a tower PC with a Ryzen 5 1600 CPU and a Laptop with a Ryzen 7 1700.
Both of them show the same behaviour.
They tend to

  • freeze when using the browser
  • reboot when using the browser, mostly when I open Save As or Upload window and start to navigate folders
    – when rebooting I get a boot message with keywords mce, microcode, cpu id

My browser is ungoogled-chromium. I didn’t have the time to test if this behaviour happens with other browsers.
I also have profile-sync-daemon running.

Somewhere I found the recommendation to set
But that didn’t change anything.

Currently I cannot access the journal of -b -2. After a reboot following hte crash I will document the journal log and port it here.

That’s my combo: AMD Ryzen 3 1200 + Gigabyte B450. I was suffering espontaneous reboots, really annoying and dangerous during and update.

Enabling AMD IBS in the bios>Peripherals>AMD CBS fixed it.
Maybe it’s related or not with your issue, but it’s an idea…

I didn’t find that in my BIOS.
But I found something different, a setting called SVM Mode with the info “Enable CPU virtualisation feature.” It was disabled and I’m using a Qemu/KVM. So I will observe if it helped now to enable that feature.
Thanks for a possibly useful hint in the right direction!


I’ve realized that now this setting has been moved a little:
Peripherals>AMD CBS>CPU Common Options

:grinning: :grinning:

No, I can’t find any IBS (Instruction-Based Sampling) in the BIOS, there is no mention in the notebook manual neither.

Just now I got a freeze while scrolling down on the Manjaro forum.
Here is the put put of journalctl -b -1

Have you been able to use these in the past without issues? Or are these new computers?

The freezing is a known issue for 1st gen Ryzen CPUs on Linux. It is an issue with the C-State if I recall correctly. Supposedly, for some people, their BIOS/UEFI updates eventually fixed it. Though… for others like me:

I have a Ryzen 7 1700x and to make it work without having the computer freeze, I had to go into my UEFI → AdvancedAMD CBSPower Supply Idle Control → Change to Typical Current Idle

Now, not every motherboard has these exact steps to find this. You’ll have to look for it. Regarding your laptop though… hopefully it has an unlocked enough UEFI to change it.


The machines were new to me and I got those issues from the start.

I wasn’t able to find any AMD CBS settings in the UEFI firmware.

Sound Server-4: PulseAudio v: 15.0 running: yes
Sound Server-5: PipeWire v: 0.3.40 running: yes

You use Pipewire AND Pulseaudio
Use Pipewire OR Pulseaudio !!!

Swap:      Alert: No swap data was found.

Create a Swapfile

I agree on pulseaudio and pipewire.
As for swap I have 32 GB RAM.

@cscs suggested that it migh have to do with IOMMU

sudo dmesg | grep -i -E 'fail|error|iommu|amd' | less

alternative link

That is a question that cannot be answered without having a look at your configuration and even with plenty of available memory, it is often used as a safety net or even sometimes due to specific application requirements so have a look at the following non-exhaustive list:

If you use hibernation: yes, you need swap!
If you have services that are not always active, but are still running all the time: yes, you need swap!
If you have an application that allocates virtual memory directly for temporary storage instead of RAM: yes, you need swap!
If you have an application that has a memory leak: yes, you need swap!
If you have a server with 1TB of RAM that you're using as a desktop without applications allocating virtual memory or having memory leaks: No, you don't need swap!

The Link is broken

I’ll try with swap. But I ran the same setup on an Intel 9th Generation laptop and had no such issues.

Is this ok so ?

sorry, the link works for me
try the alternative link I posted.

The temperatures, I don’t know.

That’s the default on KDE. Pipewire is a dependency of KDE desktop.

Some dmesg checking might be helpful. Maybe something like this:

sudo dmesg | grep -i -E 'fail|error|iommu|amd'

But taking a guess, I might say check on iommu, and the old rcu_nocbs workaround for ‘soft lockups’ as seen in the past. idle=nomwait may be applicable as well.

( )

Note: The rcu_nocbs option is dependent on threads not cores. One way to show total:
sudo dmidecode -t 4 | grep 'Thread Count'

These are all boot parameters, so apply them in /etc/default/grub, run sudo update-grub and reboot.
In this example I will assume you have 16 threads.

iommu=pt rcu_nocbs=0-15 idle=nomwait

Just throwing those out there.

( PS @eugen-b I dont think 0x0 likes being sent a ‘less’ output … I wil modify suggestion. )
( PPS oh I guess you can change tabs to RAW … never seen it before :stuck_out_tongue: )

eventual ?

I did notice

[    0.000000] tsc: Fast TSC calibration failed
[   11.578305] tpm_crb: probe of MSFT0101:00 failed with error -16

( I actually have that module blacklisted so :woman_shrugging: )

[   12.269443] iommu ivhd0: AMD-Vi: Event logged [INVALID_DEVICE_REQUEST device=00:00.0 pasid=0x00000 address=0xfffffffdf8000000 flags=0x0a00]

So those first and last ones may be symptomatic, but I assume it is before testing any of the above options.
The first one definitely reminds me of when I first got a new ryzen machine. I cant quite tell if the 3rd one also matches an old apic issue.
