Author: marius Date: Mon Dec 15 21:42:38 2008 New Revision: 186140 URL: http://svn.freebsd.org/changeset/base/186140 Log: Don't try reading the SXP_PINS_DIFF on the 10160 and 12160 SCSI controllers. Reading this register, for which there are indications that it doesn't really exist, returns 0 on at least some 12160 and doing so on Sun Fire V880 causes a data access error exception.
