Author: marcel Date: Tue Mar 10 06:21:52 2009 New Revision: 189611 URL: http://svn.freebsd.org/changeset/base/189611 Log: Fix a buglet in revision 189401: when restoring a 64-bit BAR, write the upper 32-bits in the adjacent bar. The consequences of the buglet were severe enough though: a machine check.
