This points to a problem with the PCI bus configuration.  It's probably
not directly related to the EEPROM issue, although they might both be
related to timing problems with the hardware.  (SGI has a reputation for
cutting corners with their bus implementations.  Anyone remember the
almost-EISA machines from a few years ago?)

You can change the timing by compiling the driver with  -DUSE_IO_OPS.
Please try this if possible.

Hmmm, curious -- the station address is significantly wrong.

Along with the other information.

Hmmm, I wonder who implemented this one.  The blank board number should
be 000000-000, not some made-up number.  I wonder if SGI used a slow
EEPROM, or did some other hackish thing.
