Is this on a debug kernel? If not, build a debug kernel and get the machine to crash again. Then save the instruction pointer value (0xc0527284b above) and do the following: # cd /sys/i386/compile/FOO # gdb -k kernel.debub gdb> l *0xc0527284b To find out where it crashed. Also, try running with INVARIANTS turned on. -- John Baldwin <jhb@FreeBSD.org> <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
