Installing Proxmox on a debian 11 base install, boot error with 5.15 or above kernels, 5.13 or below work

[anim72]

I want to install proxmox on a base debian 11 install with LUKS protected disk based on https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_11_Bullseye

apt install pve-kernel-5.15.85 - hangs at loading initrd

apt install pve-kernel-5.13.*, 5.15.7 - works fine

No kernel above 5.15.7-1 works, kernels below 5.15.7-1 work.

Any idea how to debug the issue?

Modules only in 5.15.74-1 initrd which are not in 5.15.7-1 initrd:
kernel/drivers/mfd/ljca.ko
kernel/drivers/gpio/gpio-ljca.ko
kernel/drivers/i2c/busses/i2c-ljca.ko
kernel/drivers/spi/spi-ljca.ko

Modules only in 5.15.7-1 initrd which are not in 5.15.74-1 initrd:
kernel/lib/crypto/libblake2s-generic.ko
kernel/arch/x86/crypto/blake2s-x86_64.ko
kernel/lib/crypto/libblake2s.ko
kernel/crypto/blake2s_generic.ko

So could that be that the blake related modules are required for the LUKS encryption based install?

The solution is to install debian, then find a proxmox kernel which boots the debian system, 5.15.7 should work, then boot the 5.15.7 kernel, and install proxmox on top of the debian system. Then newer kernels can be installed.
