Strange... have you modified the kernel? Perhaps the hook that's trying to intercept the panic call is latching on to the wrong PC for some reason. If you run from gdb the break_event should drop you into it and perhaps you can poke around and figure out why you're there.

The thing is, it happens pretty early in the boot process, where I install exception handlers, so there is no 'panic' call or handler at that time.
