  OPRASHB:Habanero:EEH: Opal not calling out slot number for failing

  ---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.

  =================================

  I have built the Ubuntu kernel with patch and created  *.deb files.

  Please find the same in the following path for installing and testing
  your test case

  ==== State: Assigned by: thalerj on 13 January 2016 12:10:58 ====

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