Lenovo Legion 15ach6h : amdgpuBusId seems incorrect

[Malix-Labs]

On my machine (a factory-modified-issued Lenovo Legion 15ach6h), the amdgpuBusId seems to be PCI:5:0:0 instead of PCI:6:0:0

[Lyndeno]

I don't have this model to test. Has anyone else seen identical models with different IDs?

[Mic92]

Sometimes Lenovo has different versions of the same model depending on the location you buy it.
We noticed it with X1 laptops bought in Europe vs UAE.

[Mic92]

Is there a way to accustom for both pcie ids?

[Malix-Labs]

Would there be a way to detect the PCI ports dynamically?
