Hi All,
I've just pulled the 2.6.27 kernel from git and am trying it out on my
MPC8313E RDB dev kit. I get the following badness during boot (the
complete boot record is attached later) :

I used the mpc8313e_rdb_defconfig, with the exception of enabling more
debug.
Any help - not sure where to start... ?
