@eselarm Thank you very much for the details. I am currently working with the NanoPi R6S minimal image, with kernel 6.1 based on your feedback. I started out with the rolling release version, but that cannot run Jellyfin (because it is Forky). So I going back to the Trixie version and test this now. I will report back here whether the Jellyfin server works well with the transcoding of 4K movies (like the vendor FriendlyElec distribution does) and whether 4K movie playing can be smooth on it.

Note that if you enable USB3, it disables PCIe. That's a hardware limitation of the a5e, I'm told...

Board that would fit though, the H4 PLUS from hardkernel, limited to 4 sata instead of 5. 120x120, but only 2 screws would fit I believe...

Update, this is also working .... extraargs=reboot=watchdog UPDATE: It stopped working after 3 successful reboots...

Ok update.. I used a USB Ethernet to update and now the local phy is showing as end0 and it works. I'm kind of doubting my story now. I know the initial login could not connect to the Ethernet. After I installed on the local emmc and upgraded via apt upgrade things work now. I think this is a non-issue.
