One thing though is that if we can fix the nested panic we might can work on the first one. > -- > Ian Freislich > > Booting [/boot/kernel/kernel]... > /boot/kernel/acpi.ko text=0x3a0e4 data=0x19e4+0x11ac > syms=[0x4+0x6860+0x4+0x8a87 ] > Copyright (c) 1992-2004 The FreeBSD Project. > Copyright (c) 1979, 1980, 1983, 1986, 1988, 1989, 1991, 1992, 1993, 1994 > The Regents of the University of California.
