Haven't had time to try that yet. I'll try it tonight, hopefully, if I
get time.

I suspect that it hasn't recognized it. It has only reached the point
in the messages where my working (1.1) kernel would recognize the pas.

Of course. It never prints any message indicating that the pas has
been probed (successfully or unsuccessfully). It never prints anything
about the pas. It just dies after probing and recognizing wd0 (or is

Thanks for the message!
