Yup? So your card is probably somewhat different from my version. 0x20
is the default index. I have other config tuples:
0x1 with IO at 0x300 this is what I use together with IRQ 11.
The other are:0x2 with IO at 0x320; 0x3 - 0x340; 0x4 - 0x380.

You are wrong. The horrible is that the autonegotiation problem gives
exactly the same kind of error one would expect from and interrupt
problem. I had exactly the same trouble with my FA410TX. As far as I
have followed the list, in 4.0-STABLE this problem should be fixed in
the ed driver source. But I'm not sure.
I have attached the fa_select.c. Caution !! The io addr. is hard coded
(see comment in the code).
Hope this helps,
David.
