SDIO probe: Error -84

[Simon Twogood]

It's a rev. B.

I'm using the latest kernel, 2.6.27 because it appeared to add a  
number of fixes for the at91_mci driver, and it's certainly working  
better than earlier releases.

The adapter card I'm using at the moment is probably not providing the  
best connection, resulting in a CRC error like you mentioned. By  
Monday I should have new boards in with the Wi2Wi module integrated  
without the need of the MMC card slot or adapter. I'll test again on  
those boards to see if the error is still there.

Thanks,
Simon
