Having some issue with accessing USB devices and made some changes of the iommu groups. Seems I bricked something.

When I am now starting Unraid, it does not connect to the network. Getting "Eth0 Does Not Exist" and "IPv4 Not Set".

Cannot provide diagnostic log as I cannot access the server. Tried to delete the network.cfg file, but no change.

Changed the USB disk with fresh install (though copying over the config folder), but issue remains.

I happened to have an old Unraid stick around, which seems to be working (but is totally outdated, so that's not an option to use).

Any idea how I can troubleshoot this issue?

Tried in "safe mode" and same issue.

It works with an old unraid flash, so it is not an hardware issue.

In parallel, the usb error is still there and may be related. I can use keyboard & mouse to access bios and select safe mode. However, once it reaches the screen to enter user name for unraid, the keyboard no longer works.

Somethind is borked in the settings?

Please post the diagnostics.

Hooray! I fixed the issue, which also fixed my other issue with not being able to access USB devices.

The root cause must have been related to prior attempts to make wifi work. I deleted the wifi.cfg file and now things seem to be back working again.

The only thing that is not working now is that my flash disk ID is blacklisted. But I guess support will be able to help on this to get it working again?

If the flash drive is blacklisted, you will need to transfer the license to a new one, but support can help with that.

Thanks. I've reached out to support to un-blacklist the device.

I do not not think that un-blacklisting is supported, so I expect you will need to transfer licence to new drive. Be interested to know if support say otherwise.

They cannot unblacklist the device; they can transfer to a new flash drive.
