Maybe it's related to the Intel NIC?
B450 and B550 are mostly the same so the platforms are very similar.

My X540-AT2 based X10DRU-i+ run fine, when they do not have NVME storage and no Connect-X3 and no ceph-osd.

So I do not see the Intel NIC as the culprit.
 
Also having problems with the 6.8 update here, had to pin to 6.5.

Hardware:
Supermicro X13DEI-T
Mellanox ConnectX-5

I am getting the following logs which seem to point to the broadcom driver for the mellanox card?:

However various processes simply crash after the machine has booted up. Network doesnt work as well.

this seems like the intel_iommu issue - does the issue remain if you add intel_iommu=off to the kernel commandline?

Yes - intel_iommu=off "fixes" it. So no change on 6.8.4-2 -> 6.8.4-3 (on Intel)

Then I think this is the resolution to the issue on that NUC.
The default will most likely stay 'on' so for systems with broken implementations disabling it is a sensible solution.

I want to be super super nice.

I am on this issue now for 4 business days with my own time, budget, brain, head smashing.

6.8.4 and 6.8.8 vanilla "zabbly" https://github.com/zabbly/linux

They work out of the box - with intel_iommu=on ... with libvirt, qemu on Debian 12 out of the box with the same hardware and the identical VMs.

So with all respect - and I really mean that with all respect (!) - it's a pve kernel issue. Not a hardware, kernel, ...

In other words ... only the 6.8.4-X-pve crashes.

That is what I am interessted to fix.

Why? If you roll out the vanilla proxmox ISO (8.2.2) on existing Hetzner hardware, you have hundreds of computers not booting. :) Some of them will eventually bekomme a Harry problem

did you add the intel_iommu=on to the commandline?
asking because the package downloaded from: https://pkgs.zabbly.com/kernel/stab...+_6.8.8-amd64-202404301432-debian12_amd64.deb
does not enable intel_iommu by default
(you can check it yourself with `grep -i iommu /boot/config-6.8.8-zabbly+`)

does dmesg on this kernel indicate that iommu is active?

I run this on 6.8.6-zabbly+ and 6.8.8-zabbly+

Only the 6.8.6-X-pve kernels crash... (Same Hardware, Same VM iso, ..)

(the difference that makes the difference is probably the qemu & libraries) but it's the Debian 12 core.

Again - willing to jump with your kernel devs in a call or work on that with a github repo. It's working on zabbly.

Hm - thanks for verifying this and for your efforts so far!

could you try the zabbly kernel for 6.8.4 (as that's what our kernel is actually based on)
and the Ubuntu 24.04 kernel:
https://packages.ubuntu.com/noble/amd64/linux-image-6.8.0-31-generic/download

one further difference I noticed in the zabbly config vs. ours is `CONFIG_INTEL_IOMMU_SCALABLE_MODE_DEFAULT_ON` is set for ours
could you try booting the PVE kernel with `intel_iommu=sm_off` (not 100% sure that it disables that part - but still would be interesting if this works on your machine)

Thanks!

Tomorrow :)

- I will create scripts to download + install the Ubuntu Kernels on Debian 12
- Probably a git repo for this.



If this isn't working - lets jump into the git kernel tree diff madness. That will be a 5 cups of coffee day - but willing to do it.

From what I understood, the zabbly kernel adds kvm patches. I get less "noise" about a broken bios (in contrast to the Debian kernel)

-------------------------

And proxmox guys - please promisse one thing.

Get some of the machines you killed (or ask Hetzner for a donation....) and add them to your QA/Unittests. It's a no brainer. They are cheap and you need to unittest them for 8.2.2 -> 8.x updates.

Ping me if you need help. I am doing this for very egoistic reasons here! I love to "make" things. We all hate (re-)fixing bugs.
 
In this thread it was asked if folks could reply to whether or not "intel_iommu=off" worked to fix the crashing

For us it does not. Booting to kernel 6.8.4 still crashes the machine hard

This is on kernel 6.8.4 .. our fix is to pin our boot to 6.5.13-5-pve at this time

Our machines are Dell R740s, NVMe only nodes with no hardware RAID, only RAID involved is ZFS mirrors for OS .. Ceph is directly accessing NVMe drives

Ceph version is 18.2.2

Current working kernel is 6.5.13-5-pve

Hope this extra bit of information helps

Thanks

do you have any logs from the crash? - else it's hard to see where the issue is rooted...
also did you try `6.8.4-3-pve` ?- this got released to the no-subscription repository yesterday and contains quite a few fixes.

Ubuntu kernel

wget -c -t0 http://de.archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-modules-6.8.0-31-generic_6.8.0-31.31_amd64.deb

sudo dpkg -i linux-image-6.8.0-31-generic_6.8.0-31.31_amd64.deb


sudo update-grub

  • I select the "generic-6.8.0-31.31" in the Debian Grub Boot menu
  • The kernel boots
  • basically "nothing" works - no wifi - no X11 (only in 640x480)
  • libvirtd errors (I have no idea why and I don't care why)
  • We have a /dev/kve
BUT: The PVE kernels (without any VMs!) crashed at this point. No VM started - just after boot. Check my logs :)

Here my suggestion.

Let's wait for a final reaction of @t.lamprecht or @Stoiko Ivanov - I am willing to fix the problem whatever it takes.

I am on day 5.

> Unfortunately my suggestions to jump with a Proxmox Kernel Dev in a debug session didn't get an answer.

Are you skilled to help / do you have someone in your company willing to help?

Next steps are clear - build 5-10 test kernels based on the Ubuntu kernel and leave out the proxmox patches - test them.

I run gentoo 10+ years. I know what todo - but - I have no idea how the pve build system works.


Greetings from Denmark.

It's just me at home on a day off. 6.8.8-zabbly+ won't boot because it lacks ZFS and Ubuntu-6.8.0-31 does not come with amdgpu(?).
I tried the Ubuntu 24.04 installer (with kernel 6.8.0-31) and it also crashed the GPU when amdgpu is loaded automatically. So my issue is an upstream kernel 6.8 or Ubuntu issue.
I could try a nested Proxmox (without ZFS) and GPU passthrough to test further, but it looks like Ubuntu kernel 6.8 is just an unlucky choice (at the moment).
