Nothing was committed that would affect reported PCI parity errors.
It may be that your chipset just doesn't generate parity correctly.
It may also be that the card edge is dirty or the slot is.  Hard
to say.  The parity error reporting can be disabled if necessary.
I'll look into adding a device flag for that in the near future.
