Hi,

my system:
X470d4u
AMD Ryzen 5 3600
Samsung M391A4G43MB1-CTD 2666 MT/s 32GB
PSU be quiet! System Power 9 400W
BIOS Version 3.5
only power cable and one Ethernet Cable within LAN1 Port
no VGA cable or USB devices plugged in

I upgraded BMC from 1.90.00 to 2.20.00 via IPMI and didn't preserve any configuration.

Problems with new firmware:
- System Inventory is blank no information available in all sheets
- KVM several times "network connection" lost from client zu server in the system boot process

I tried "Maintenance->Restore Factory Defaults" -> nothing changed

So I downgraded back to 1.90.00 via IPMI
- System Inventory works again
- KVM seems to work without connection loss

With both setups no information from the PSU.

I still have the challenge, that debian testing (bullseye) with Kernel 5.10.0-2 running, the system doesn't poweroff after shutdown.

Any suggestions?

kind regards
Axel
