What errors?

The only fix in v1.12 works around what appears to a bug in certain '559
chips that causes the machine to hang when the interface is first started.
This problem does not occur when the driver is compiled with -DUSE_IO_OPS.

Note: I/O operations do not go through the write buffer, and thus have
slightly slower timing.  The '559 only has one documented timing
requirement, and that's a brief delay after triggering a reset.  So this
problem really looks like a hardware bug.

The fix is only for linking pci-scan.o into the kernel.
It does nothing if pci-scan.o is loaded as a module.
