Yes, cdc_mbim, just shortened it in writing here... Removing it now.
From version 6.12.4 to 6.12.6. I realise that was not the clearest way of writing that. The first diagnostics file was from after installing the driver to show that things were installed correctly, the second file is after the upgrade to 6.12.6.
The modprobe thing, is what I mentioned earlier of seeing the message "modprobe FATAL: module r8152 is in use" during bootup of the unraid server. Followed shortly by the 2 minute stop at the udev portion of boot (forget the exact words). Figured it was worth mentioning.
I did not type in a command that you guys did tell me to, just to be clear. Im no linux guru, but this isn't my first time with a CLI.
Ran the command blacklisting r8153_ecm. Rebooted, things were fine, and then ran the upgrade tool for Unraid 6.12.6. And it seems the r8153_ecm blacklist did it! Everything booted as it should, and I can remotely access the server!
Thanks you so much for the help! Sorry if I wasn't super clear.
Anyhow, I included the diagnostics of the confirmed working configuration in case you guys wanted to pick it apart a bit more.
