Author: jhb Date: Mon Jun 24 18:30:44 2013 New Revision: 252166 URL: http://svnweb.freebsd.org/changeset/base/252166 Log: Disable hw.pci.realloc_bars by default. It wasn't needed for the original tester of this fix, and realloc_bars breaks some other cases as a small BAR that is reallocated can end up grabbing space needed by a much larger BAR in the existing window of a PCI-PCI bridge.
