Author: marius Date: Sun Jan 10 18:39:29 2010 New Revision: 202023 URL: http://svn.freebsd.org/changeset/base/202023 Log: When setting up MSIs with a filter ensure that the event queue interrupt is cleared as it might have triggered before and given we supply NULL as ic_clear, inthand_add() won't do this for us in this case.
