I had the same problem, where I had built my kernel with *both* wd2/wd3 and wcd0/wcd1. The probe for wcd0 failed every time until I rebuilt with wd2/wd3 commented out as Steve has done. -- Tom Russo WWW: http://www.swcp.com/~russo/ Never put off until tomorrow what you can do today, because if you do it today and like it, you can do it again tomorrow.
