---Problem Description---
Working with Chad (IO team) we were able to inject an EEH recoverable error
to the broadcom network adapter (PE #2) behind the PLX switch. Looks like OPAL
calls out the Backplane PLX ( Planar ) instead of the adapter slot.
We want to primarily focus on why the adapter slot ( behind PLX )
didn't get called out using this defect.
Problem:

It seems you're disabling memory BAR and then issue MMIO load, which results
in "unsupported request" returned from the adapter. In response to that, the
PE#2 as shown in the kernel log is put to frozen state. Nothing wrong at this
point. I think the only question would be: the location code isn't making
sense.

The patched kernel is working great for both firestone and Habanero.
It resolves the issue and all slot numbers are called out properly.
