Do you mean it's already long enough (95.7ms) for this case, and waiting longer won't solve the issue?
I don't know, I just want to get rid of the possible bug causes.

I'm not a PCI expert. So let me ask.
From the following AML, RTLK/LNKS belong to a PCI register space:

Can you infer what it is from the above AML?
