VM freezes irregularly

[Snk B]

If you don't need ultra low power maybe some i3/i5 devices are also suitable.

This kernel bug wasted me many hours and now ive decided to settle down and use it solely for routing and simple network management maybe sometime in the future, there could be a fix for this device, but now I will just give up on it.

And the thing that I've really learned from it is I will definitely carry-out full-fledge research on the device I'm going to buy

Really... It took me many, many hours of work and research... I'm tired.
Mainly because my wife is always complaining that she has no internet to work from home and when I see pfsense it is broken.
My Ubuntu server VM, broken
My Windows Server, with kernel panic.
I'm putting my unit up for sale and I'll get another one with the N6005 version that apparently doesn't have these problems.
I need stability, even more that I run my firewall virtualized.

Exactly the same for me... Women ....

If she didn't work from home, she wouldn't even have such a problem. But the worst thing is this home office... Anything, it's a reason to call me at work and say that the internet isn't working.
Just throw my minipc out the window haha

My wife was giving me a hard time too. Every second day she was complaining about the internet not working but since I've moved to the new kernel, she hasn't said a word. Before throwing the PC out, you should definitely try the edge kernel - it's super easy to install.

There's also issues with the N6005 - if you read through the servethehome forums, quite a few of the guys in there were complaining about stability and heat issues with it.

Yes, I remember how the first versions of the N6005 were, I think V2... They were ES/QS and had a lot of problems.
Looking at STH, apparently the new versions V3 and V4 no longer have thermal problems (and I believe they won't have kernel crash problems like N5105 either)

Update from my NUC11ATKC4.

I updated to 5.19-edge kernel two days ago and the four testing VMs are running fine since then.

Many thanks to Fabian for releasing the edge kernel.

Unfortunately after 2 days 22 hours one of the four testing VMs froze on my NUC11ATKC4 with N5105 and edge kernel.

The other three VMs are working fine so far.

I understand I am on a home-lab/niche hardware so I won't be asking for any effort, but - in case - I will be available to perform any test.

The VMs which froze is this one, when it froze the CPU was at 50%.

n5105 pve host running 3 vms:

• debian 11 with some containers in it.
• win 7 vm
• win10 vm

win 7 & win 10 vm are very stable, while the debian vm keep freezed in randomly time. logged in kdump

RIP: 0010:asm_exc_page_fault+0x0/0x30

while the same vm was very stable in previous j3455 pve host.

What kernel are you running on the host? If you're not running the edge kernel (5.19.x), upgrade to that. It's been rock solid for us.

5.15.39-4-pve, but #206 said the problem still exist with edge kernel. and I've migrated all containers to a LXC container.

I think he's the only one who's had an issue and from memory he built the kernel so who's to know if he's missing some configuration options.

95-99% of us who've upgraded to the edge kernel have had zero issues. My Ubuntu & pfSense VMs have been up for a week without issue.

Err... If you must know, I was the one who built the kernel myself and I am apparently not the other PVE forum member who is also suffering from this issue in #206.

Also, should the kernel be different from the one provided by pve-edge-kernel's repository, the only possible explanation is that the source is not consistent with the one Fabian's built with, which I, myself, I don't believe at all.

Besides, there are at lease 3 members(including me) who have had freezes on 5.19, and the rate of that, though my maths might not be so good, is IMHO much higher than 1-5%.

5.15.39-4-pve, but #206 said the problem still exist with edge kernel. and I've migrated all containers to a LXC container.

And by the way I'm not saying this issue can be reproduced 100% since many have benefited a lot from this updated kernel and it certainly worth giving it a try. So I'm personally looking forward to seeing how it would perform on your machine and hopefully we can have some ideas on what exactly caused this problem.

And one more thing, Fabian just released kernel 5.19-6 with more patches from upstream. Maybe you could give that a shot to see if it performs better or what.

I think you've mistaken my comments as being some attack against you which I can assure you they weren't It's hard to keep track of who's VMs are freezing on 5.15 or 5.19. I assumed that nearly everyone who'd installed the pre-built edge kernel had no more freezes but if I'm wrong then I apologise. Either way, the 5.19 kernel has been rock solid for me and quite a few others.

 

[k-123]

alright, I've just installed kernel 5.19.6-1, and started 2 debian VMs.

 

[rRobbie]

I also upgraded my NUC11ATKC4 to the latest edge kernel (thanks Fabian).


A mix of 6 testing VMs are running (Ubuntu, Fedora, Opensuse).



I will keep you updated over over the next days, meanwhile I am available for specific trials.

 

[darkrayacc]

Ubuntu VM crashed after 5 days on 5.19.4-edge kernel. I only have two VMs- one pfsense another is ubuntu with few docker containes.
I will update the kernel amd see if this improves.

 

[k-123]

2 debian vms did not freeze in 24 hours, at before they won't make it. just upgraded to 5.19.7-1.

 

[CPUGoingZoomy]

Just chiming in - I too have the same issue described above (VM crashing - Proxmox seems unaffected).
This is with a Aliexpress "Topton" N5105 unit. Opnsense VM seems to only crash when some traffic is active and NICs connected to Proxmox bridge.

 

[BarTouZ]

So far, I'm very lucky...

Everything works perfectly and it really feels good to be able to use this little machine... It reacts really well with this nvme!

after upgraded to 5.19.7-1, pve died once (cpu is not busy at that moment), debian guest vm freezed once in 8 hours. changed guest cpu type from 'host' to 'kvm64', hope that will last longer.

My NUC11ATKC4 so far has been stable with 5.19.7-1 (from release to now), have you considered to run a memtest on your system? Just to rule out a RAM issue.
