Author: marcel Date: Fri Oct 23 22:53:01 2009 New Revision: 198431 URL: http://svn.freebsd.org/changeset/base/198431 Log: BIOSes, buggy or otherwise, are i386 or amd64 specific. Have the early USB takeover enabled for i386 and amd64 by default. This also avoids a panic on PowerPC where the resource isn't released properly and we find a busy resource when the USB host controller wants to allocate it...
