I'm not handy with gdb, but I'm thinking this is what you might want? #38 0xc026fc9e in vm_object_shadow (object=0xd73782e4, offset=0xd73782e8, length=847873) at /usr/src/sys/vm/vm_object.c:1058 1058 if (source != NULL && (kgdb) print source $1 = 0x0 Is that correct? Is there any additional information you would like from the previous panic? Thanks, Charles > -- > Doug White | FreeBSD: The Power to Serve > dwhite@gumbysoft.com | www.FreeBSD.org >
