    Just did a search about this message around the kernel source tree.
    The interesting thing is that I see the following comments at several
    different arch/drivers files. Is it related to your problem?

    * Known BIOS problems we have to work around:
    * - I/O or memory regions not configured
    * - regions configured, but not enabled in the command register
    * - bogus I/O addresses above 64K used
    * - expansion ROMs left enabled (this may sound harmless, but given
    * the fact the PCI specs explicitly allow address decoders to be
    * shared between expansion ROMs and other resource regions, it's
    * at least dangerous)
