This most likely will have absolutely nothing to do with your problem, but the 
error messages are quite similar to those seen on a problem I had with a SATA 
device. It turned out in the end that the device defaulted to using INTx 
emulation, and by asking it to disable it made it work... it would but take you 
a minute to rule it out at least...

The patch we hacked in for it is attached, will not work "as is" at all, but 
could be adapted to yours.. The essentials are that we print out the CSR and 
check if bit 0x400 is set (listed as INTx in Linux), then unset it and send it 
back out.
