Doug, try my infamous "probe the PCI_BASE_ADDRESS" patch (attached for
0.89H) to see if it fixes this.  I recently noted (the hard way, of
course) that as of 0.89H it is still necessary for a number of our
systems here with genuine 21140's (the old KNE-100's) in dual PPros.
Don swears that probing the ioport to ensure writability should not be
necessary and of course he is right, but this patch has worked for
everyone who has tried it and at the very least makes the
insmod/rmmod/insmod ritual unnecessary by basically incorporating it
into the driver.
