Actually, in this case, I dont get that message. Just the same 'effect'.
iostat shows no activity, although the bonnies are still running, just
doing nothing. If there is there some extra information I can provide you
with, let me know what you want me to do.
STATE and WCHAN show D and getblk
iostat -c 100 shows
newmail# iostat -c 100

even though they are still running.

is all I did. How long do I have to wait normally for the wedged message
to show up ? The last time I saw it was with the 428, but I seem to recall
the message showing up fairly quickly
e.g.
