        if (reply_len != reply_buf_size) {
                /* Too much or too little data received */ 
                return (EMSGSIZE);

This should read:

aha0: INQUIRE failed 0x28

since 'error' is printed in hex.  Why we're printing errors in hex I don't
know (other than to make me waste 10 minutes tracing down bugs that don't
exist that is.)

Now, anyone have a good idea why AOP_INQUIRE_BOARD_ID is getting too much
or too little data?

Andy, try changing sys/dev/aha.c:aha_cmd() so that the test before the
last return() looks like this:

        if (reply_len != reply_buf_size) { 
+		printf("reply_len %d, reply_buf_size %d\n",
+		       reply_len, reply_buf_size);
                /* Too much or too little data received */ 
                return (EMSGSIZE);
        }        
                 
        /* We were successful */
        return (0);
}               

And show me the line when the error occurs.

> aha0: Card not responding!

I added this message for some reason or another.  Its not really helpful
at all.  :)

I've rewritten the bt_mca driver to hopefully do the right thing.  I was
trying to avoid excess code but I'll worry about trimming stuff down
later.

Get the new versions of {aha,bt}_mca.c and recompile.

Thanks for doing such a good job of testing!
