Author: imp Date: Sun Dec 7 18:34:27 2008 New Revision: 185741 URL: http://svn.freebsd.org/changeset/base/185741 Log: Use '0' rather than PZERO to not change the priority that I'm waiting at. I don't think this will make a huge difference, but I have received a report of a interrupt storm on one 16-bit card that this might fix (chances are it won't, since I think that we may need to check both the CBB registers for the 16-bit card as well as the PCIC registers for power state change).
