I have been experiencing a few performance and stability issues with the latest kernels and find that, for now at least, the older 5.4x kernels work a lot better with my hardware. I recently updated to the latest 5.15x kernel and while doing this I also checked to see what others are available. I see that since running on Bullseye, only Bullseye kernels are available.

My question is whether it’s possible to use older 5.4x kernels with Proxmox7/Debian11 Bullseye and if so, is there is anything wrong in doing this (other than the obvious - latest updates etc). Would the mismatch work? Would I be better off using Proxmox 6.4 if I want to use the older kernel?

TIA!
