[Gardner Bell]

Immediately after booting into 6.2-RC2 my system froze up and dropped
into ddb.  Here is the relevant information.  If any further info is
required please let me know.

I had to manually type this all in as I don't have a null modem
available where I am.  Please Cc me as I'm not subscribed to the list.
