Andy,
Attached is the file with the debug=321 data. Let me know what else I
can do. I am very willing to provide you any data you need to get
this driver working for everyone.
Something is really wrong with your PCI(e) bus or your CX23418 chip's
behavior. Here's what debug=321 looks like on my machine:

You get the picture hopefully. Whatever was written to the CX23418's I2C
control register over the PCI bus is what we should immediately read
back. On the next entry to the function, the upper 3 bytes should be
the same.

All the values being read back are wrong. In fact, the values read back
are always either 0xf or 0x7 depending on which CX23418 I2C control
register, RD or WR, is being read.
You have a PCI bus problem, a problem with your CX23418 chip, or the
driver just isn't initializing the CX23418 properly.
My immediate suggestions are related to finding possible PCI bus
problems:
1. Try a different PCI slot
This might be a clue. This is a Dell OPtiplex GX240 small desktop.
Since this is a small case the only two PCI slots are on a riser card.
Does that make a difference? FWIW...I did swap PCI slots with no
improvement.
2. Try the card in a different motherboard if you can, to rule out the
possibility of a bad card
I have two possible options. I could install Win2k on this machine
and see if everything works. I also have another, newer (Dual core
AMD, 2GB RAM) box running Fedora 9. It's the kids computer so I'll
need to fight them for it. I'll try to do one or both of these in the
next day or two.
3. In the output of lspci -vv look for error conditions in the "Status:"
(>TAbort+ <TAbort+ <MAbort+ >SERR+ <PERR+) on the CX23418, the CPU host
bridge, or any bridge in between them (or on any device).
Here is the result...

4. Make sure the latency timers for all the PCI devices have reasonable
values.
Not sure I know what is reasonable....Any guidiance? Can I change
latency settings?
Maybe others on the list have other ideas.
I'll have to ask Hans about how to verify the CX23418's I2C hardware
block is getting set up properly.
Regards,
Andy
