Usually these bugs are a NULL pointer deref that can often be easily fixed if we can find out where it happened. Actually, though, the ip can be found from the tf_eip member of struct trapframe, which is 0xc05d1e69. Can you send the output of 'l *0xc05d1e69' from gdb on the same kernel.debug? -- John Baldwin <>< http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" = http://www.FreeBSD.org
