Are you using the netbsd.gdb in the kernel compile directory?

Yes, that does seem to work. Weird that -g doesn't. Here's the panic:

And here's the addr2line output:

Again, this is netbsd-7. I can attach these source files if needed. Here's the versions:

(andy@)[/usr/src/sys/dev/usb] $ head -1 usbdi.c
/* $NetBSD: usbdi.c,v 1.161 2014/08/05 06:35:24 skrll Exp $ */
(andy@)[/usr/src/sys/dev/usb] $ head -1 if_athn_usb.c
/* $NetBSD: if_athn_usb.c,v 1.6 2013/10/16 18:23:39 christos Exp $ */

Thanks!
