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.

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!
