The 3c509 can automatically find the I/O address and IRQ of the 3c509
card.  You should not fill in any fields.

The IO1 IO2 DMA0 and DMA1 fields are meaningless.  If you fill those in,
the invalid parameter will prevent the driver from loading.

The problem you are seeing has been reported before.  It seems to be a
bug that Red Hat introduced.  (The driver they are shipping has been
modified from my version.)

That's an important clue..
