This fixes the panic. It appears there's also another bug in dump though. When I run dump I get this: [10:15pm] brooks@minya (~): sudo dump -a -f /dev/null /var Password: DUMP: Date of this level 0 dump: Wed Jun 5 22:16:09 2002 DUMP: Date of last level 0 dump: the epoch DUMP: Dumping /dev/ad0s2e (/var) to /dev/null DUMP: mapping (Pass I) [regular files] DUMP: mapping (Pass II) [directories] DUMP: estimated 580085 tape blocks. DUMP: dumping (Pass III) [directories] DUMP: dumping (Pass IV) [regular files] DUMP: master/slave protocol botched. DUMP: The ENTIRE dump is aborted. Any idea what this problem is? -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
