Just updated PVE from 9.1.6 to 9.1.9 and to kernel 7.0.0.3 and got kernel panic.

I pinned the kernel to 6.17.13-2-pve for now and I'm back to business.

I'm happy to provide details to help to debug .Just tell me you need.

I updated to Kernel 7.0.0.3 I have the Problem when 2 VMS with UEFI and Mapped PCIE devices are start the 2nd VM will kill the first one. Meanwhile other vms can be started and run without problems. I reverted to 6.17 and all went fine again. II attached the log with the 7.0.0.3 kernel - its seems to be a repeating pattern.

I see some memory limit error but with 6.17. I still have over 30GB ram free and 700GB on the SSD

I am using:
AMD Epyc 8434P
ASRock Mainboard SIENAD8-2L2T
Broadcom HBA 9500-8i

So i tried kernel 7.0.2-2 but the problem still persists.

I think I met the same isseu like yours, all VMs are running with maximum cpu, then make host run with maximum cpu, it make the pve machine unstable, I have to pin 6.17 as boot kernel.

And I have another pve machine with 3090 GPU, the GPU cannot be detected on kernel 7.0, with the same driver installation switching to 6.17, then GPU is running well.

I have 5 pve machines which have upgraded to kernel 7.0, above 2 meet those issues, another 3 are good.

A update for my 2 issues.
Both of those 2 machine were using 2021/22 BIOS Version, so I have upgrade both BIOS to the latest version.

Now, high cpu usage on kernel 7.0 issue is gone. and I also update kernel to 7.0.2-2-pve, and the performance is goold.

But for kernel 7.0 does not detect GPU issue, it is still here. Is it driver issue? Maybe not, I have one usecase on another PVE, that is passthrough RTX 2000 to an ubuntu 26.04 VM, it is also kernel 7.0, and the RTX 2000 works well.
The different of the driver:
PVE installs the driver from nvidia "*.run" installer, the ubunu install driver from "ubuntu-drivers" installer.
