Aloha Dinesh

I tried it but it doesn't help. Does this work for you?
Are you running 5.2.1?

Start with 8MB SM card in da2.

For what it is worth, here are the most recent entries in /var/log/messages.
The same group of messages appear whenever I perform the mount command
whether I am mounting an 8MB or attempting a 128 MB card.
