Hi Proxmox community,

I experience these random freezes multiple times per day on new Dell Optiplex 3000 (12th Gen Intel(R) Core(TM) i5-12500T). I have tried different kernels and BIOS settings but it doesn't help. I also updated newest 09/02/2022 BIOS (1.5.2) and disabled power states, WLAN, Bluetooth etc. but still Proxmox crashes with or without VM's running on it.
It was stable on june and july, then I was travelling on august and when I came back I did update/upgrade and it started to crash.
When it freeze / crash, it doesn't even ping, I have to do hard reset.

Let me know If there is more information I could provide to help solve this problem? BTW Is it possible to try older 5.13 kernel with proxmox 7.2? if, how?

thanks

I would suggest to test your hardware. Memtest86 and else to rule out hardware issues.

I forget to mention that I did full Dell BIOS HW diagnostics and Memtest86 like first thing and they both were OK.

I'm running now 5.13 kernel and see it that crash too.

Now it's been 1 day and 19 hours, still no crash with 5.13 kernel! Also with VM's everything runs fine.

So there is some problem with 5.15 and 5.19 kernels because it used to crash multiple times per day.

Any ideas how to proceed? just use this old version and wait if future kernels works better?
 
Make sure the system journal is persistent and see if you can find any kind of log message just before the crashes. Then you have something to search for and maybe someone somewhere already found a work-around.

Wild guess: try using the intel_iommu=off (also disabled passthrough) or iommu=pt (uses the same mapping for non-passed through devices as when IOMMU is off) kernel parameters, as 5.15 started enabling IOMMU by default on Intel (but maybe newer versions reverted that change).

With 5.13 kernel it was up 2 days 22 hours withour crashing. I added intel_iommu=off to /etc/default/grub to a line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=off" and did update-grub + reboot, but it still crashed.
I changed it now to iommu=pt

I can't tell from this, but IOMMU does look disabled. Check if cat /proc/cmline matches the kernel parameters you wanted to set.
As I said, it was just a guess and it appears that an enabled IOMMU was not the problem (as disabling did not resolve it).

EDIT: I have no clue where to look next.

Still crashes, I've tried intel_iommu=off , iommu=pt and intel_iommu=off parameters on 5.15.60-1-pve and 5.19.7-1-pve kernels.

Example of params:
root@prox:~# cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-5.19.7-1-pve root=/dev/mapper/pve-root ro quiet iommu=pt

What should I look next?

I guess I just use 5.13 kernel until I can try 6.x kernel. Can't figure out what cause the crashes. Dell hardware is new and OK and work properly. Everything was fine before I updated proxmox to 7.2.
I also reset all BIOS settings and tested disabling features but nothins seems to work except running kernel 5.13.

Here are errors rows from proxmox journalctl logs if someone can tell what is wrong:

I think I finally solve the problem or at least found a workaround.

If I go BIOS settings and disable C-Power states, it does not crash anymore. I test this on 5.19 kernel.

On BIOS:
Performance / C-States:
Switch called Enable C-State control (Feature enables the CPU's ability to enter and exit low power states)
Set this to Off (default is on)
