Went from an Intel based Sandy Bridge CPU to a Ryzen 8600G with Asrock B650M HDV/m.2 board.

UNRAID does not show the GRUB menu on startup for some reason. I can't access the GUI using the web interface, so I typed "slim" on the normal interface and got into the normal GUI.

I notice that the time is wrong and not syncing to NTP server, and the temperature sensors are not showing anything on the dashboard indicating some hardware detection issues.

UNRAID does not appear to connect to the router. On startup I spotted the message "eth0 device not found" (I paraphrase)

It seems the root of the problem is a loss of network connection. I tried deleting network.cfg, but that didn't fix anything.

How do I go about troubleshooting this?

If this is going to be a complicated fix I don't mind starting afresh with a clean USB flash drive with no dockers and no shares. Will doing this solve the problem?

What steps do I need to follow to create a clean UNRAID installation on the existing USB and reinstate the licence?

I appreciate any help on this. Thanks.

You are likely to get better informed feedback if you attach your system’s diagnostics (with everything in the one zip file) to your next post in this thread. It is always a good idea when asking questions to supply your diagnostics so we can see details of your system, how you have things configured, and the current syslog.

Here is the diagnostics file.

You are blacklisting the Realtek NIC driver, and that board has one, so the driver is not loaded. Delete /config/modprobe.d/r8169.conf from the flash drive and reboot.

You can delete it from the CLI with

rm /boot/config/modprobe.d/r8169.conf

Thanks. I deleted the file once but after restart I still could not enter webgui. Went into the folder again and found the same file back in there. Turns out there was a Realtek drivers plugin, which I deleted (I forget what it did). Then I went back into config and deleted r8169 again, and this time it worked and I have webGUI access. Awesome!

Do you know how I might troubleshoot the no CPU and motherboard temperature problem?

I don't see a temperature for CPU and MB on dashboard

For the CPU you can upgrade to 7.3.x, for the mb a plugin would be required, assuming it supports your board.
