Do you know if anything changed in the PCI code that might affect
the initialization of PCI devices?  It is almost as if some of our
PCI register writes are not being honored (e.g. prefetching has
suddenly been enabled for this card even though the prefetch bit
if off in all of its BARs).  6.2.1 has been in the kernel for some
time and was not changed in going from .10 -> .12.
