--- Comment #38 from Franck Rousseau <Franck.Rousseau at imag.fr> ---
Hi all, some additional information on this crash.

The procedure that I describe in the previous post crashes consistently, which
is a good point to start debugging. I suspect the crash to come from internal
structures that are left corrupted at some point, after which there are several
symptoms, like cannot intuit interface, no memory allocated, and ultimately a
kernel crash.

I have compiled a new kernel with DDB support enabled, hopping to be able to
inspect memory at runtime, but the address of the (struct rtentry *) is
different each time. Does anyone has an idea on how can I get the address that
I need to watch to track who is modifying the routing table?
