Have you tried setting the CPU type to EPYC-Genoa? According to the best to use for you would be either EPYC-Genoa or x86-64-v4 (enables AVX512)

Please add it to the guides like https://pve.proxmox.com/wiki/Windows_2022_guest_best_practices

Okay so we have more instances of Intel CPU bug related crashes now: My instance of Intel 13900 CPU crashes here in this thread (motherboard: ASRockRack W680D4U-1L) Another one @dakralex showed me here with Intel 13900K: https://forum.proxmox.com/threads/153793/ by @Crash1601 Another one I've...

Hello fellow Intel 13900 user. I already had a similar problem on one server on November 27th 2024 (https://forum.proxmox.com/threads/kernel-panic-after-upgrade-to-8-3-kernel-stack-is-corrupted-in-kmem_cache_alloc-0x37b-0x380.158134/#post-727767), now I got another problem on a different server...

Ja, bei mir lag es in der Tat ebenfalls an der Hardware. Mit neuer CPU+Mainboard+RAM+SSDs läuft der Server fehlerfrei! Siehe https://forum.proxmox.com/threads/kernel-panic-after-upgrade-to-8-3-kernel-stack-is-corrupted-in-kmem_cache_alloc-0x37b-0x380.158134/#post-727767

The old server hardware was faulty! At first, Hetzner tried to keep the old hardware and just do some settings in the BIOS (which looked promising too): But directly after a fresh PVE 8.3 install, I got the same old error again: Therefore I chose the option to change all hardware, including...

Hey da geht es dir sehr ähnlich wie mir und einem Hetzner EX-101 mit Intel 13900 CPU. Habe lange memtest86, Disk Checks und CPU Checks gemacht, alle fehlerfrei und ohne Anzeichen von Problemen...

Wow this looks super similar to my PVE 7 test at https://forum.proxmox.com/threads/kernel-panic-after-upgrade-to-8-3-kernel-stack-is-corrupted-in-kmem_cache_alloc-0x37b-0x380.158134/post-727108 I got some general protection fault and lots and lots of segfault instances, too. So that's it -...

I don't have 8.1 to try, but installed PVE 7.4-1 from https://enterprise.proxmox.com/iso/proxmox-ve_7.4-1.iso Installation is a pain, had to use the quirks from https://forum.proxmox.com/threads/generic-solution-when-install-gets-framebuffer-mode-fails.111577/#post-541768, and for some reason...

PVE 8.2 has the same problem, directly after installation. So I guess my "system" (CPU? memory? I have no idea anymore, because my stress tools havn't found any problems) is somehow instable. At first Hetzner provided me with the wrong USB stick, a PVE 8.3 again, so I've installed that one and...

before testing PVE 8.1/8.2 again, I did some further CPU tests overnight: # 1 hour test CPU root@rescue ~ # stress --cpu 32 --timeout 3600 stress: info: [33029] dispatching hogs: 32 cpu, 0 io, 0 vm, 0 hdd stress: info: [33029] successful run completed in 3600s # 15 hours test CPU root@rescue...

This is the result of Hetzner's Full Hardware Check: Dear Client, The hardware check was completed without any errors. Please see the results below: -----------------%<----------------- Hardware Check report for IP xx.xx.xx.xx CPU check: OK CPU 1: OK Temperature: OK Clock speed: OK...

Thanks a lot for your replies! Before doing further testing, I had already asked Hetzner for a BIOS/UEFI upgrade, and apparently they did something, see Release Date from 2024 (I rent the server since 3/2023, and it was never down for any maintanance from Hetzner, so they must've done it): #...

Here another screenshot from another crash: Here another one: Another one: Another one: I have some more but I think they all look pretty similar. Is the server hardware somehow faulty? Or is it a Proxmox problem, like PVE 8.3 being not compatible with this system? In case of a...

That's not the problem. I've just installed PVE https://enterprise.proxmox.com/iso/proxmox-ve_8.3-1.iso on the same server freshly: After installation I directly encountered the same problem again: Then after a hardware reset, the system booted surprisingly without a problem. I've entered...

Today I tried to upgrade a server (Hetzner EX101, with Intel i9-13900) with PVE 8.2 to 8.3 via the Web GUI. The server is not part of a cluster. I can provide you the PVE license number if needed. Hardware configuration: 2x 2 TB NVME in ZFS RAID1 (root), 2x 8 TB NVME in ZFS RAID1 (for PBS...

Einer meiner PVE hosts war nicht mehr via Web GUI erreichbar, ist komplett gecrasht (im Syslog stundenlang keine Einträge mehr) also habe ich den Hetzner "Automatischer Hardware-Reset" genutzt, um einen Reset auszulösen und das System neu zu starten. Ich habe folgendes in /var/log/kern.log...

thanks for the quick reply. I've opened https://bugzilla.proxmox.com/show_bug.cgi?id=4646

To be precise: The sync job on host A (which pulls data from remote host B) does cause lots of proxmox-backup-proxy logging on host B, not on host A. I have the same problem, because several servers sync data from a host about every 5-10 minutes, so on the host that data is being pulled from I...

Thanks a lot for your solution, and the details! I just want to add some detailed instructions, and provide another example of bus IDs, so maybe my example helps out someone: I am using the brand new Hetzner EX 101 which includes a Intel® Core™ i9-13900, and tried to install Proxmox...
