Hi,

I successfully run VE to 8.1.3 fully updated to kernel 6.2.16 on Msi Z790-P + 14700K.
However, i have a need to downgrade to 5.15.53
I disabled "safe boot and run through"

downloading kernel from 7.x
Code: 
wget https://mirror.cs.uchicago.edu/proxmox/dists/bullseye/pve-no-subscription/binary-amd64/pve-kernel-5.15.53-1-pve_5.15.53-1_amd64.deb
wget https://mirror.cs.uchicago.edu/proxmox/dists/bullseye/pve-no-subscription/binary-amd64/pve-headers-5.15.53-1-pve_5.15.53-1_amd64.deb

installing
Code: 
dpkg -i pve-kernel-5.15.53-1-pve_5.15.53-1_amd64.deb
dpkg -i pve-headers-5.15.53-1-pve_5.15.53-1_amd64.deb

applying
Code: 
proxmox-boot-tool kernel list -> verified installed
proxmox-boot-tool kernel add 5.15.53-1-pve
proxmox-boot-tool kernel pin 5.15.53-1-pve
proxmox-boot-tool refresh

and now my computer hangs on trying to load the kernel
Code: 
loading initial ramdisk ...
even the cursor stops blinking

I can still boot when I manually select 6.2.16 or other installed 6.x kernels

what could be the problem?
too old kernel?
too new hardware?

Hi,

The only officially supported kernel for Proxmox VE 8 right now is 6.5.

Why? It's not even the latest 5.15 kernel, but more than a year old and missing a lot of (security) updates: https://git.proxmox.com/?p=pve-kernel.git;a=shortlog;h=refs/heads/pve-kernel-5.15

I have been told that I need 5.15 to ensure airdrop on mac VM
but eventually I run Ventura on the latest kernel and it works
apparently the only issue would be to use WiFi on the PCI card - but I am happy with cable connection
