PVE 8 to 9 upgrade issues, need help with recovery

[eroji]

I have 3 Minisforum MS-01 hosts running PVE 8.4.14, with Ceph running on Thunderbolt links between the nodes. I went ahead with the 8 to 9 upgrade following the docs https://pve.proxmox.com/wiki/Upgrade_from_8_to_9. Starting with the first host, I went through the process but upon reboot, it indicated that DKMS service failed to start. I was able to get into recovery mode and remove the i915-sriov-dkms module. Moreover, all the interfaces were down for some reason. I edited /etc/network/interfaces and give one of the NICs a static IP and was able to get it to connect just so I could run apt commands. After removing the module and rebooting, it no longer showed the DKMS service failure, but it just sat at the boot screen (see picture below). If I try to boot into the recovery mode again without entering the root password, it gets stuck trying to start networking.service. I'm pretty stuck at this point and hoping someone could assist with getting the node back up.

Here is my `interfaces` config.

# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

Ok I was able to figure out the issue. The thunderbolt interface.d configuration was the culprit. The old config did not seem to want to work with 9. Checking the page I got the instructions from https://gist.github.com/scyto/58b5cd9a18e1f5846048aabd4b152564 it seems to be updated and has a new version, which is working as it did previously.
