I re-did the acpidump with Linux on the same machine. It goes smooth. But FACP
shows DSDT as 0 (opposite to what I said earlier). Other than that, I could
dump all tables properly in Linux.

Had a quick check about PCIe config space access from _INI method (from the
dump collected with Linux). As I understand, seems there is no PCIe config
space access from _INI methods. But, I will just confirm again about that. The
backtrace for address 0xb is same as what I posted here earlier(for 0x24). I
will try to understand that path.

Will keep you posted.
