Oops: kernel access of bad area, sig: 11

[Joakim Tjernlund]

Hi all

Just pulled bk:linux_ppc_2_4  and ported it our  custom MPC860 board with
128MB RAM. Booted the new kernel and did a compile to test the kernel and
ggc got signal 11 and an Oops( see below).
The same "port" works for Monta Vistas kernel hhl 2.0(based on 2.4.2)

Any ideas what migth be wrong?
