Author: jkim Date: Wed Feb 15 22:49:25 2012 New Revision: 231791 URL: http://svn.freebsd.org/changeset/base/231791 Log: Set up an event handler to turn off speaker if user requested it. Speaker will stop beeping after all device drivers are resumed. Use proper API to "acquire" and "release" PIC timer2 for consistency and correctness.
