Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   My system:
Mainboard: Fatal1ty B450 Gaming-ITX/ac
CPU: AMD Ryzen5 2400G
Memory: 32GB
NVMe: 480GB
SATA: 2x4TB and 2x1TB
Additional Intel IGB300 NIC Card with 2 Ports

The IOMMU GROUP NUMBER are correct until to the BIOS Version 3.70.

After the update to V4.10 will this made a mismatch in the number order.

I have this tested on Debian and Archlinux, from Kernel 4.9 to 5.9, always the same.
The option ARI in BIOS have no effect to this.

The menu point "Advanced\AMD CBS\FCH Common Option" are completely missing in V4.10.
On V3.70 I can see in this menu my additional NIC card and can change the availability of the ports.

If this a bug or a incompatibility with the AMD Ryzen5 2400G CPU?
