Since the upgrade to kernel 5.15.x, due to issue like these,

https://forum.proxmox.com/threads/kernel-bug-cpu-soft-lockup.110059/
https://forum.proxmox.com/threads/proxmox-7-watchdog-hard-lockup-cpu.111725/

I would like to try to install and boot the 5.13 kernel.

Code:
apt install pve-kernel-5.13
proxmox-boot-tool kernel pin 5.13.19-6-pve
proxmox-boot-tool refresh

Good.
But rebooting the server, even if the systemd-boot menu show the 5.13 menu entry, the default (selected) one is the 5.15 one and the system boot with it if I don't manually select the other one.

The result of proxmox-boot-tool kernel list is

Code:
Manually selected kernels:
None.

Automatically selected kernels:
5.13.19-6-pve
5.15.35-2-pve

Pinned kernel:
5.13.19-6-pve

Where do I go wrong?

hi,

can you try running:
Code:
proxmox-boot-tool reinit
proxmox-boot-tool refresh
to see if that makes a difference?
