New Revision: 190810
URL: http://svn.freebsd.org/changeset/base/190810
Log:
When multiple cards are present, register a shutdown handler for each card
instead of just register one for the first adapter. Without doing this
there would be some data loss upon shutdown because data could be ignored
when flushing to disk.
