Hi  Christian

But when amdgpu driver is unloading, it will call this function.

And driver unloading is an legal case under SR-IOV.

Do you mean PCIe device removal indicates the unplug the real device?

Yes, exactly and that is not supported.

Sounds like the error message is then on the wrong place.

Christian.

NAK, that error message is not related to fbcon but means that PCIe
device removal is not supported.
