Proxmox does not start after upgrading to 6.8.4-2

[kalnas]

After upgrading kernel to 6.8.4-2 server not starting:



Selecting 6.5.13-5 kernel works fine. My GRUB already had intel_iommu enabled and is working fine with 6.5 kernel

GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt"

Any tips how to get 6.8 working?
