The routes command reads /proc/net/nr_neigh to get the info from kernel.
You should be able to verify that this indeed causes the problem by
reading it with eg. cat: cat /proc/net/nr_neigh
This should cause a segmentation fault and the kernel oops as well.

This is really strange. I can't think of anything else but recompiling and
installing the kernel + modules. Maybe one of the modules or the kernel
binary itself is corrupted?
