    Just a follow up on this: this appears to be an Illumos bug, though I
    haven't figured out how to resolve it yet. The problem appears to be
    that Illumos doesn't recognize any PCI bridges beyond those attached to
    CPU1. Notably, nothing on CPU2 appears to work. I've tested with Linux
    3.5 and that works flawless, attached are the lspci -vvvv outputs.

    The problem appears to be that Illumos stops after PCI address 0b:00.0
    (on-board MegaRAID SAS 2208). After that the scan should proceed with
    the QPI inter-processor links, but doesn't.

    The full lspci should look something like this:

    Can somebody please recommend how to debug this issue?
